//but if we do ever decide to work on our R, I can't keep telling him that he was wrong for doing so//
I went back and read a lot of your story. I am not sure what it is about your XH that draws you so close to him. Is it his looks, his charm, his money? I can't tell. The only thing I see when I read your posts is his Selfishness.
I think selfishness is at the core of MLC or WAS.
I decided to file because I just realized that I don't want to put any more effort or time into a relationship with someone who is in love with themselves. I will never be loved or treated the way I deserve by a person that always puts themselves first.
I agree that you will never be able to convince him that what he did is wrong. I just wonder why you are willing to settle for someone who thinks treating a marriage partner like that is OK.
You are divorced and starting over. You get to raise your standards. I know I am going to.
When I remarry, it is going to be with a person who loves God, who shares my values, who views marriage as commitment for life, and who has demonstrated through a lifetime of actions that they are willing to put others before themselves.
That man is out there, and it is not your XH. Time to let him go.
