What does it mean if guy always hangs out with girls in front of you?

Probably nothing. Don't read too much into it is what I am trying to say. If you are the girlfriend just make sure you give him room to breathe. He may just like your friends as much as you do and in the same way. I believe that is possible. If he is going to cheat there is little you can do to prevent it anyway. Either he is or he isn't. DON'T lose your dignity along the way. You can't control him so don't try to. The only control you have is self control. Just be happy he likes your friends. Don't make too much of it. If it turns out it's something more that's ok too. That's why you are DATING anyway... to find out if he's worth marrying.

AnswerMy boyfriend hangs out with my best friend all the time. She actually sees him sometimes more than me. Don't sweat it. If you know you're girl and you know your guy - then it shouldn't be an issue at all. However your girlfriend should always respect you and your relationship. If you start to feel uncomfortable make sure they BOTH know, don't keep it to yourself. If they love you like they say they do, then it won't be an issue any longer.

Be confident.
