How to deal with guys hitting on your girlfriend?

[Anthony]

I have this amazing girl who i was lucky enough to have become my girlfriend.I trust her with all my heart.But i constantly see guys post on her facebook wall how pretty she is or post <3. She told she's never cheat but ever since one of my precious relationships im very insecure and have that fear she will cheat. How can i help get over this fear?

There isn't much you can do I don't think, you might as well pretend it doesn't bother you and just take it as a compliment, remember that at the end of the day she's your girl, no matter what other guys say, if she thinks your insecure about it she might start feeling held down, it's like telling a kid not to get into the cookie jar, only makes them want to more.

Well if you have her listed as your girlfriend on FB that would be a good start. Also sometimes but not to often you can do what the other guys are doing and post on her wall about how pretty you think she is also include somehow how she is your girlfriend. OR when a guy post's about how pretty she is you can comment on the post along the lines of "Yeah I think my girlfriend is pretty too" lol just a thought.

Tell her that bugs you. She might tell them to stop or just delete the posts.
