In my opinion,it all depends on how mature the guy is...but other than that could be two reasons : 1.he told you he liked you,did not receive any sort of response - and was hurt.therefore,chose to avoid any more "pain" by stop talking to you. 2.he told you he liked you for a certain reason,didn't receive the response\reaction he wanted\needed.therefore,he stops talking to you - because he sees no point. But,on a more serious note,I think that a person that genuinely cares about you (without you doing anything harmful,mean to him) wouldn't stop talking to you. Send him an email,explaining how you feel about the situation and ask him if he'd like to meet so you can talk about it like grown ups in a mature way.
he likes you girl
He likes you.
He might be. Then again, he might not. The only way to know is to ask him.
When he talks about sex with you. When I was talking to a guy, he flat out said "would you ever get with me?" but they usually talk about sexual things.
When he stops talking to you/looking at you
It usually means that he likes you and considers the other guy a threat to his chances with you. but it depends on what the guy you like said
yes and/or no. Yes! It defenitly does, that guy is teasing the guy that you think likes you!
Why do you think he likes you?
If a guy's talking to you on the phone, then he likes you. Period.
Usually if a guy spends time on you, that means he likes you. This could mean teasing you, doing favors for you, talking about you, or just plain talking to you.
If a guy looks at you a lot, he probably likes you too. If he stops when you look at him, maybe he is shy, but maybe he doesn't want to flirt with the girl his friend likes.
If he said he likes you already...go for it.
