What an absolute pos wife. Omg.I was talking to a buddy over the weekend who is suffering from cancer. His wife is having an affair because she thinks he can't give her what she wants anymore. The dude was always faithful, made good money, and they have five kids. Doesn't matter: she feels entitled to another guy, a fantasy romance, and happiness at his expense. My buddy tried explaining to me that they had an "agreement" and that he loved her and wanted her to be happy.
OP, mate. You're a soldier. Stand up straight, chest out and walk the hell out of her life. She's gross, you deserve so much better than this, it's just not right.
You WILL get through this, please be sure to heal completely before you embark on another relationship, your future wife shouldn't have to pay for the sins of the one who came before her.
