I have a male friend, who for the life of me, can't figure out how and why he's still single.  After spending a night on the town with him, I realized what the problem is-he's a complete idiot when it comes to female body language!  Here are 5 signs that will tell you if she (or he depending on your wants) is really that into you.

1)Eye Contact.

You know the kind, the one that seems a little too long to be normal, if it lasts more than a couple of seconds, that person is definitely digging your action. Related to this, after they look away if they fidget (flipping hair, adjusting clothes etc)-then they were definitely nervous and caught in the act.  

Side note:If a persons pupils dilate when they look at you, they are attracted to you (it's totally subconcious and can't be controlled).  However lighting does interfere with this, so if it's a bright room or out in the sun, this might be hard to tell.

2)Facial Expressions

Aside from pupil dilation, there are other facial gestures that can indicate attraction-slight parting of the lips or nostril flare, the obvious batting of the eyelashes, but if a person is touching their face, that also is a sign-it means they want to draw your attention and have you check out their face.

3)Posture Changes

We all want to look our best when you want someone to check you out,  so most people tend to stand or sit straighter (better posture makes your body look better).  Quite primal, but some women subconciously (some not so subconciously), thrust their chests or lean against something, to accentuate the curves in their body. Men tend to thrust their chest (quite tarzan isnt' it?).  Another clue-check out their feet and positioning, if her they are pointing towards you, or they are leaning into you,  your company is being enjoyed.

4)Check the Palms

I found this quite interesting, but if a woman shows you her palms or wrists while talking to you, it is actually a form of submission.  Hey don't shoot the messenger ladies, it's what most body language experts say, when it comes to the rules of flirting.

5)Body Contact

Ok, I think this one is obvious, if that flirtatious giggle wasn't enough, then all the touching must clue you in.  We're not talking a body thrust (although you'll be surprised what you see in New York sometimes!), but if a gently touch on your arm, hands or dare we say it, face, are definite signs that your action is being dug!

There you have it, 5 signs, now go out there and have some fun!
