Backstory - An ex of mine who I've known for 10 years (we've stayed friends) told me from the beginning he was damaged because his ex who he lived with at the time ran off with his best mate and left him heartbroken. Said he hated any kind of infidelity. Recently he's told me about one of his mates who frequently gets drunk (and drives) to meet women from swingers websites while leaving his partner sleeping at home. More recently, he told me another good friend was crashing at his. I was surprised as this was a man who I've always believed was happy in his marriage with 2 young children so I said "Oh no, that sounds sad" I was told I'm fact no, it was a good thing. Because mate left wife. Mate had met someone else. Been unhappy for around 4 years. Only spent one night in my exes spare bed before moving in with the OW.
Is it just me, or does it appear to be ok for men to cheat, whereas women are all snakes with tits if they put a foot wrong?
