Good read, glad you're posting. I will say, if we knew our situations were to end in divorce, that most would probably want to just file and get it done with, "You didn't fire me, I quit!"... buttttt we all need time to truly heal. Some here don't do that and go back to the ways that haven't worked. That's humans for you.
If you're still skeptical of relationships, I think you may have more healing to do. Sounds like you and your XW both have a wall up. Perhaps this is still showing in your interactions with the XW.
Love requires vulnerability. Eventually you should get there.

It is not things that bother us, but the stories we tell ourselves about things.
