Glad to hear things were civil, at least for one night. Do not be surprised if it takes a turn again. I am glad to hear your STBX is getting help. If only my STBX would seek help things may change but in my case, she is too stubborn and proud.
AS for me, I go to court tomorrow to try and get custody of my S. My STBX has been using my son as a weapon/bargaining chip and I have seen him 5 times in the last month. It has truly gotten ridiculous but things hopefully will start going toward a conclusion tomorrow.
Keep doing what you are doing. Take care of yourself as well as your D. Over time, you will figure out what you want. It might be to keep trying with the X or move on. In the long run you will be better off.
As for the support and advice, when I was in your place, I had someone on this board in my shoes now and they helped me. Just stick with this and help someone out when you get the chance...
