After church today I had a talk with my stbxw. Thanks to some nice people on reddit I was armed with lots of questions and counter points. And it really help me drive home to her this isn't fixable. The best we can hope for is to be civil when we absolutely have to deal with eachother.

She cried, pleaded, begged and cried some more. But by the end of our talk I think she better understands the amount of damage she has caused me and our daughter. Will give her some time to give up on this reconciliation nonsense.
