labug is giving you some good advice so I would take it. I am in much the same situation as you except we both moved (found places that were only 5 homes apart for kids) about 2 months ago. I have been given a lot of good advice on here and part of that was from labug. If I remember right I was instructed go go out and purchase a few cans for STFU when I pushed my W too much. Even small comments tend to have a big impact.
I am sure she knows how you feel. Best thing you can do is focus on yourself and your kids.
Let go and just maybe....
Don't give up!!!
