Well I don't have kids so I will tell you what has happened to me.
Things got easier when my W moved out. There wasn't that constant reminder right in my face, I was able to do things around the house without having to worry "will this push her away more." I still have to see her because she is getting her things and honestly, it really doesn't hurt that much now. Yes, it [censored], but there is nothing I can do and she is going to do what she is going to do.
We have not been intimate since I couple of days before her BD. Personally I would say stop doing that, but I haven't been in your shoes so who knows. Right now it seems like you two are always communicating (about bad memories), keep in mind all he sees is the bad and all you see is the good, R talk should be stopped IMO.
Lastly, do you want to have kids with THIS MAN? Even before all of this? If your answer is no, then buh bye. Also, do you really want to have kids or do you want to try and keep him around (not trying to be mean, just asking). Finally, you will never be financially stable to bring a child into the world. You will give up everything for that kid but if you can barely afford yourself right now, then do not bring a child into that.
Detach, GAL, and PMA...what are things you enjoyed doing before M?
