My wife is divorcing me because monogamy can't make her feel fulfilled.
My(M31) wife(F28) and I have been married for five years and together for six. About a year ago, she told me that she wanted to try opening our marriage because she felt that she didn't get the opportunity to truly explore her sexuality before we got married and felt that if she didn't, she would regret not doing so. I told her I wasn't okay with this and that I wanted to keep things monogamous. I suggested that we go to couples counseling but she did not want to. We fought about it for a couple weeks after which she apologized to me and said that she was being selfish and that it wasn't fair to put me in that situation. I hoped that would be the end of it. She brought it up a few times since but always in a sort of joking way so I didn't think much of it. probably around two months ago, she brought it up again, adding that she felt very unfulfilled and thought that if she didn't explore sex with other people that she would grow to resent me. She would constantly ask me to explain why I'm not okay with non monogamy and while I would do my best to express why I felt that way, she began to dismiss my thoughts as closed minded and told me she thought I was still brainwashed by purity culture (we both grew up evangelical). This time, she agreed to go to couples counseling so we scheduled an appointment for the first week in June and went on with things as normal. We even took a trip over memorial day weekend which was great. Two days before our first counseling session, she told me that she had cheated on me with a guy that we are friends with. I felt absolutely devastated by this but still wanted to try to figure things out. We went to our first appointment but she decided to divorce me before our second appointment. She told me over the phone that our marriage was over and then immediately invited the guy she cheated on me with to spend the night with her. She apologized to me for how she handled everything and says that I'm still her best friend and wants to remain friends but I just don't see how that is possible. I moved across the country because she took a job in another state and pretty much all of my friends here are people that I know through her and her family. two months ago I was happily married, now I'm living on my own a thousand miles away from all of my friends and family going through a divorce that I didn't want. I just don't understand how she could treat me like this after everything and destroy our life together so that she can sleep with whoever she wants to. I have no idea how to move forward from this. I love her more than I know how to say but have never felt more hurt by anyone in my entire life.
