I need your advice on something... two guys are trying to move in on my girlfriend and every time she tells them to get lost, they think she's flirting with them...

What the can I do? :(

Maybe she should just ignore them all together, they seem to like attention

You just can't stop some people from making themselves into a horse's behind... :)

If I were in your shoes, I would have fun with it... Tell your girlfriend, "I'm going to the bathroom now, let me know how many guys hit on you while I'm gone..."

When someone says there not interested, its not normally considered flirting. But two guys think so? She may be saying she's not interested it but how is she saying it?

Keep on eye on her and see if she really isn't trying to flirt with them. How is your guy's relationship? Other than that, just try and keep her away from them and if they come near, tell them to lay off your girlfriend. Hope things work out.

All that matters is that she is YOUR girlfriend.

Other people will try and break it up I'm sure. Just keep an eye on her and thoes guys.
If you and her ignore the both of them, they will get bored and move on sooner or later.

I think you should go kick some a** . They are messin with your girl, come on!
