My ex left me for his affair partner. He didn't ask me to forgive him because he wasn't sorry. Still, I offered complete and unconditional forgiveness initially. My reason was that I knew he had to be seriously mentally effed up to have done this to me and our family. Like, needing mental health help, counseling, and medication level messed up. Like, when this hits him someday and he has to face what he has done to me and our kids, he might kill himself level screwed up.

He did not take me up on my offer to forgive him, and left anyway. I am glad he didn't, because I can see now, that he would have just cheated again and again, it being his go-to coping mechanism for life's difficulties.
