boyfriend means nothing? so if you have a gf you wouldn't mind if she hooked up with another guy... didn't know you were a green hat
First of all I don't really do boyfriend girlfriend relationships. I keep it very casual.
Secondly if I did have a girlfriend its because she wanted to stay and if she wanted to go with some other guy I wouldn't keep her anyway. I am not some desperate virgin there is plenty of fish in sea.
If she cheats on you then its because she isnt serious.
Boyfriend girlfriend isnt a serious arrangement in my eyes just a couple of tyre kickers. Either you commit or gtfo.
