Me [50M] have learned to let my [49F] wife cheat. Better than divorce

e (50) my wife (49) big pale fat ass great tits, chubby curvy type, community person, smart, soccer mom bitch boss type have had a crazy past. We have been together for over 30 years. Initially when we were young I cheated. Since that time I have paid for it tenfold. It started when we were young. I knew my friends have all fucked her before me. I was stationed overseas in the military before we met . Moved back to our small community and met her and heard the stories. I caught her cheating with her supervisor on the ambulance. He was married probably 55she was 24 at the time. He sent her an email saying thank you for being a good slut and letting him cum all over her face. ( I have many of her stories like this) To get to the point, when we I found out she cheated it was blow ups, divorces once, I moved she followed almost a cycle. I attempted to open up our marriage, she floated with the idea then always backed out. Saying "I just want you to want me" blah blah The last time I thought she was into something I left my iPad recording why I was gone for the week. When I listened to it, my mind was blown. My friend her assistant came over almost immediately after I left and just totally owned her. The first wires the iPad detected after hearing her walk in, him knocking and saying hello. Then I could hear her from the other bedroom saying "get in here and fuck me"! Now our sex life is pretty vanilla (between us) so what I heard was crazy. He literally had her begging to be fucked, told him to spank her; he was calling her a bitch and she was grunting and squealing like I never heard before. This went on throughout the weekend. At least 5 more times. This is where my thinking changed. When I first listened to that recording I was pissed. I also ended up jerking off endlessly listening to it. I chose to take a different approach and not say anything. Like I said before she shied away from opening up the marriage. She but tech savvy an all. So now it doesn't take much I kind of keep track of what she's doing and let her do it. Recently, besides her assistant, many of her affairs have been with married men. I seen the latest she was messaging a guy, him sending videos of himself jerking off. She was literally right here with the family when the Facebook message from him came in. I seen it on Lap Top. She got up, while we were all watching football, said she had to take a shower went in the bathroom, turned on the shower. I then seen she sent him a message, while we were all sitting in the living room of her laying on the bathroom floor stuffing her pussy with a dildo and sucking on a vibrator. She has many victims (unlike the call them) like this. I don't say anything and just let her do it. She doesn't know I know because for some unknown reason to me she can't stand the fact of me knowing. I'm sure a few times I have fucked her cream pied pussy and I live every minute of it. I just observe and get off on it. Maybe I'm crazy but I enjoy it. She is now considering a traveling job in a different state and "I can't wait " ????
