My girlfriend is always hanging out with other guys how do I stop it?!

So, my girlfriend is really hot, and weve been going out for about 4 months, and I noticed that she is always flirtin with other guys! I ask her about it and she says she doesnt know what im talking about and that she loves me. She said it was just how she was brought up by her cousine. What do I do to make her stop?!

I'm type of girl thats guys say "you are such a flirt" to but in all reality I never feel like I'm flirting. There is no way you can make her stop if she is anything like me cause she never really knows when she is "flirting"! Girls and guys have a different perspective of what flirting really is...a guy might think it is a girl talking with another guy and the girl laughing and the girl may think it is "rubbing" up on a guy. You can talk to her about it but in general I bet she doesn't really realize she is flirting. And if she is really as hot as you say she is then she obviously could be with just about any guy that she wanted to be with. You should be flattered that its you she wants to be with, that obviously means she honestly loves you! If you continue to feel insecure then you should probably move on cause your trust truly isn't there in your relationship.
