So...she cheated on you almost from the start of the marriage. But wasn't happy to find that you were also cheating on her?
You two talked about open marriage but both decided to cheat instead, even knowing in theory you both agreed with open marriage?
She wants to continue having sex, boyfriends, whatever, while being assured that you're sitting home waiting for her?
Your life and decisions are revolving around giving her anything she wants and making any sacrifice for her happiness while she disregards yours...why?
You feel you have gotten some good experiences and personal growth out of all this. These women you dated, had sex with, and then dumped because your wife with her boyfriends didn't like it...did they also get something good out of it, or did they end up feeling used and/or like disposable toys?
