How to know if a girl is into you(Guys only)

Be bold and initiate a short chat. This will help you to
learn those little things that will come in handy later
because everyone loves knowing that someone actually
listened to them and cared enough to remember the small
details about them. Listen carefully and be attentive to the
things she tells you so that you will have them for future
reference. As you talk, notice if she gives you any signs,
special words or hints.
All girls are different. Is she shy or outgoing? Does she
act like this around other guys? Look at her body
language. Leaning in, uncrossed legs, nervous voice, and
dilated pupils (especially), are all signs she likes you.
Another sign is if she laughs at your boring, stupid
jokes. (Beware: Don't use bad jokes as a test, or you'll
risk looking like a comedy dork.)
She may not be able to look you straight in the eye. She
might smile and laugh a lot because she is worried about
giving too much away.
Check for the smile. A girl that's interested in you will
usually immediately smile when you start a conversation
with her. The smile may disappear quickly if she's shy,
but it's hard to hide an unexpected strong emotion. If
she's not romantically interested, she'll likely look at you
inquisitively, but she won't express any particular
interest.
Watch for signs of flirting. If she's flirting, she may be
difficult to read. Gregarious girls may flirt with guys who
they consider to be just friends. Uninitiated, this general
interaction can sometimes be misconstrued as a crush, so
know how she acts around other guys.
Be aware that some girls have no idea that they're
flirting. In this case, she probably likes you a great deal
since her subconscious is letting her body language do
the talking.
Most girls don't like to be obvious. Girls fear rejection
too.
If you fancy a girl, never make the mistake of "flirting
around". If she sees you putting your arm around
another girl or sees another girl hugging you, she will
assume that she doesn't mean anything to you and will
stop trying.
Check for random hugs, reserved mostly for you. Hugs
can be a very openly and permissible affectionate way of
getting closer to you and touching you without it necessarily
compromising her stealthy flirting. In turn, you can go along
with it if you want, or just act busy like you're late for an
appointment and need to rush off.
Take notice if she "accidentally" bumps into you more
often than what you'd consider the usual. This ploy is
ancient and tried and true, as it's a way of touching you subtly
and sizing up how responsive (and perhaps even how well
toned) you are. If she finds excuses to touch you a lot, then
you're probably on the right track. Act casual when she
bumps into you and say "no worries" or something similar. As
for touching your arm and hair in a casual but rather
meaningful way, there's really no need to say anything; just
lap it up graciously.
Not all girls will feel comfortable reaching out using
touch. In this case, don't assume that she doesn't like
you because she doesn't try to touch you. She may be
too nervous to touch you yet. Don't be shy––break the
touch barrier yourself.
She may also find other reasons to touch you, such as
by lightly hitting you about the head, or soft punching to
the body. These "one-of-the-mates" moves can be a
thinly disguised way of getting closer to you without it
being too evident to your friends and hers.
Observe the way in which she looks at you. If she likes
you, she will tend to either hold her gaze on you for a
long time or pull away immediately the moment your eyes
make contact with hers. Either of these responses could mean
that she likes you. If she pulls away quickly, it often means
she is nervous or not ready to reveal her true intentions yet,
but she still likes you. And if she holds the stare, and you
believe you see responsiveness or even love in her eyes, then
she is confident and she may make the first move.
Of course, some girls might just be staring or winding
you up, so don't think she loves you and wants to get in
touch with the real, inner you. Use the context to discern
the motive.
If you happen to glance at the girl and you see her
staring back at you, then this means that she likes you,
although she may quickly dart her head in a different
direction.
Look at her friends. If you see most of her friends
glancing back at you and smiling or giggling, this
probably means that she has told her friends about you and
they're "in the know". This can happen at any age, although
mature girls and women friends tend to behave in a slightly
more circumspect way, using glances and knowing smiles or
nods instead of giggles. In some cases, a friend may actually
be bold enough to come and tell you that her friend likes you.
When she is having a conversation with her friends, and
you come over, she might stop talking all of a sudden.
This likely means that you were the subject of the
recently ended conversation.
If she likes you and she told her friends about you, they
might come up to you and start a random conversation
about things such as: Who would you rather date me or
(her name), who do you like better, who is the hottest,
would you marry (her name) or me, etc. If they name a
list of about three people and her name is in the list, she
probably told her friends about you and they're trying to
search for clues to see how you feel about her.
In teen years, if her friends are loud and immature, you'll
most likely hear "(your name), (her name) likes you!"
Do be aware that her friends might be making it up just
to tease her. Listen for things like: "Stop teasing me!" or
"Be quiet! He might hear!"
Look out for moments where you can play "rescuing the
damsel in distress". If you're outside and the girl you like
is nearby and starts loudly saying "I'm cold!", that's a subtle
hint that she wants you to give her your sweater. This is a
very sweet gesture, especially if you want to show the girl that
you like her. And sometimes a girl will pretend to be really bad
at doing something, and say that she can't do it. That is your
chance to offer some assistance; be aware that she will most
likely be doing this on purpose just to see your reaction and
hope that you will help out.
When offering assistance, if there are other guys around
and she actually likes one of those guys, she might be
disappointed when you offer your coat to her first or
offer your assistance. In this case, at least you'll know
how she feels and can move on. You might even be
magnanimous enough to tell the right guy that she
fancies him.
Smile at her. Girls tend to like guys who smile, and are
happy. Use your natural smile; you don't want to freak
her out. If she smiles back politely, or frowns and looks away,
she may be uncomfortable or disinterested. If she returns a
soft or big smile and continues to look at you, then it's likely
that she's interested. However she reacts, it cannot hurt to
keep smiling her way. Eventually she'll get the message that
you find her charming and she may feel able to open up more
or at least to tell you openly that she's either interested or not.
If she smiles then darts over to the crowd of her friends
and hides in the group, then she may be nervous and
curious about whether you know that she likes you.
Watch her body language. You can learn a lot about a girl
by observing her body language and it goes well beyond
obvious flirting signs into unconscious signals of attraction.
There are a lot of signs that will tell you she's interested. For
example, if a girl has her torso turned towards you in an open
manner, this means that she is confident talking with you. If
she has a closed body position, namely crossed arms or legs,
she may be shy or nervous to talk to you or she may simply
be creating a barrier to ward you off. Invest in a decent book
on body language to help you learn how to accurately read
her.
Watch for subtle signs in the girl's face––if her eyes are
dilating, then she may really like you.
When you are both in a room-- if she sits diagonally from
you or across from you at the room,when she's
interested, her torso is facing you in an open manner, or
her shoulders and hips are facing you. Either of these
signs may mean she likes you. When she is sitting and
she has her legs crossed, watch her feet, if its pointed
towards you, it might mean that she likes you and wants
to get closer to you.
Look at her lips. If she touches them constantly or bites
them, she's probably very interested in you. If her lip
quivers slightly when you look at her, you can almost be
sure she likes you.
Notice the little things she does for you. If she's
always there for you when you need help, even like
when you mention that you're really thirsty and she quickly
offers you a sip from her drink, she might like you. But don't
assume that she's into you only from one experience. Ask her
occasionally for small things, like chewing gum or a pen, and
notice how she reacts. If she's always ready to offer you
something you might need, go further and ask her to help you
with something else, like a school, college or work problem. It
shouldn't be something really easy to solve, but not too
difficult either, as some girls might say that they don't know
how to help you with a more challenging problem. If she's
eager to help you, she probably likes you, although if you use
this approach too much or choose tasks that seem too
difficult, she may think you're lazy, testing her or even a bit of
a nuisance. Don't overdo it; you don't want to risk her ceasing
to like you.
If you decide that she does appear to like you, confirm
it by having the courage to go and talk to her. Many
girls feel too shy or nervous about what your reaction might
be to start a conversation with romantic undertones. Even if
she seems like the most confident girl you know, she may
have had a bad experience in the past or simply not be ready
to approach you yet but will be receptive if you start the
conversation first. For more ideas, see How to ask a girl out .
Finally, but importantly, avoid over-analyzing her
behavior. Doing so may result in your becoming
obsessed with simply "winning her over", rather than getting
to know her as a person. Rather than investing tons of time in
determining whether or not she likes you, just take
opportunities every now and then to spend time with her and
her friends (not excessively though, or you may appear to
have no social life of your own). Basically, get to know her as
a person first and foremost and maybe things can go from
there later––starting off as a friend gives you a chance to
connect on a more real level. Just make sure to make your
intentions relatively clear (via subtle flirting), or else you may
become permanently "friend-zoned".
