It depends. If you think your girlfriend could be having an affair with another guy, you should be completely honest with her and ask her straight out what's going on. Rather than go yelling at the other guy, go straighten things out before jumping to conclusions and getting yourself in a huge mess.
they think of you only as a friend or they are cheating on you
If he kisses another girl, then he probably likes her, hugs are sometimes a sign of friend ship :)
he clearly does not love you, i suggest get another guy!!
i think its bad, because they can do anything when they are alone..you know what i mean
make the girlfriend look bad
that means that he is intrested in you and hugs his girlfriend till he says bye and gets together with you
You are jealous wen your girlfriend talks to another guy because you are insecure.
EITHER THEY LIKE YOU AS A REALLY CLOSE FRIEND OR MAYBE AS A GIRLFRIEND.
It means he likes you or thinks you need a hug; don't read too much into it.
they get a lot of hugs.
No, it doesn't. I've hugged countless guys and that doesn't mean that something is going on with them. Unless, of course, you see touching; then you can be concerned.
