I Cheated and Now I'm Being Punished

My Wife discovered that i had been sexting with another woman that i met on my other reddit account and she proceeded to kick me out of our home. A few months later after living in a shitty motel room, she invited me back into the house and i thought that everything was back to normal except during Dinner when she invited her Personal Trainer (That i pay to train her) over and told me that she's been having sex with him since i left.

My Wife loves to cuck me with strangers. While i was in hospital, her and her lover came over and started making out Infront of me and sometimes it got even more wilder. I love my wife and she's an amazing human being but she loves sex with strangers and the fact that i know about it and even see it happen.
