How can guys tell if girls are really interested or just being nice?

Well I can tell you what I do. When I'm interested in a guy:

- I'll want to be around him as much as possible.
- I'll somehow work situations with him in conversations with people as much as possible.
- I'll have a hard time looking him in the eye.like I"ll look down alot.
- I'll blush and/or smile.
- I'll touch you alot.
- I'm shy around you.
- I'm always open and honest and anxious to tell them things about myself.
- If I'm brave enough Ill ask you for help alot.

I find I touch the guy as much as I can. Even something as simple as a brush on the arm while laughing at something he's said. And eye contact! I love looking into the guys eyes as much as I can!

This depends on if she's either outgoing or shy.

An outgoing girl will flirt with you and you won't know if she REALLY likes you, unless she treats you differently than other guys.

Shy girls tend to wait to be approached, but when you flirt with them they'll flirt right back and they'll always smile. They'll laugh at your jokes and maybe eventually become more shy around you because they feel more vulnerable. (I'm shy so I should know, haha.)

All in all, no matter what type of girl it is, she will smile at you, listen to you and talk to you about more than your ordinary "small talk". She'll want to make conversation with you and know more about you. If she just acts polite and doesn't start a conversation with you, she's most likely uninterested or shy. You have to really look at the details.

Does she make the initiative and flirt with you? does she flirt with other guys in front of you and ignore you? Does she seem to focus her attention on you fully and look you straight in the eye? ask her friends as well. You can tell by her sincerity.

If she flirts with you and laughs at your dumb jokes, she's interested. If she half-laughs and is merely polite, she's probably just being nice.

Look up "indicators of interest". It's a social dynamics / pickup artist term for when women give off signals that they're interested. They're pretty similar to the little "tells" people do when they play poker.

There are so many it's literally impossible to post them all here, but to get you started little things like touching their hair, laughing at your bad jokes, staying to talk when the girlfriends all go to the bathroom, touching your chest or leg, and things along those lines are indicators that she's interested. Most are subconscious things and usually women don't even realize they're doing it.
