Thank you for posting, I have been wondering how you've been doing.
I am glad that your plans to leave have been falling into place, and I hope that despite this massive distraction with his mother that you are able to keep moving forward. You cannot predict what's going to happen or how it will turn out, but you can keep focusing on you, your daughter, and your future. I don't envy the position he is putting you in; stay strong. Sending good thoughts your way.
