Depends on how you see it bud, I wouldn't know how you feel so I'm not going to judge or make assumptions, but all I can say is do what makes you happy dude. Chicks who fuck around- got no respect for them whatsoever!
Buddy! No worries man, fuck bru, a game is way less important than your gf. I'm really, really sorry to hear that bud. You don't deserve kak like that boetie.
