because he still has to be around his friends. friendships are more complex then relationships.
If he shows other signs that he likes you he probably likes you.
"and shows signs of liking"It seems you answered your question yourself there. If he shows signs that he likes you, go for it.
If he shows signs as smiling winking and tries to make physical touching and complementing then you can tell he likes you.
Have you tried asking him? That's the only way to know for sure.
Maybe he likes you as a friend, and there is always a possibilty that he is gay. Don't take it personal. It sounds like it is about him.
Hes afraid to make a move
If she really likes you she will always look at you and give you secret smiles. But you have to show her that you like her back other wise she will feel stupid.
She likes you, she is showing signs that she is comfortable around you.
maybe she likes you or maybe she's not use to seeing you with other grls yet. cuz it's kinda weird when you get out of a relationship and you see ur ex flirting, well i think it is.
He's trying to get you to get his girlfriend to break up with him
Good indicators are that he seeks eye contact, and communication. Other signs might be he inquires if you are in a committed relationship, or shows up where he thinks you will be, or asked friends if you might be interested in him. He may make a point to catch your eye and smile. The good signs are subtle.
You should show signs that you like him (flirt), and then if he shows you signs that he likes you back, then that means he must be interested.
