did you use a Divorce support group? I did a search on DivorceCare and there are a few groups in the area but only at the local Churches, if you went how was your experience?
I did go to one of the DivorceCare groups and they are all hosted by a church. It was good to interact with people that were going through some of the same experience as myself and be able to know I was not alone. I am not a huge church person so some of the message filtered in biblical terms did not mean much to me, but some of the coping mechanisms were helpful. I had an amiable divorce compared to a lot of people there, so I counted myself lucky.
I have not read all of your previous post, but you sound like you are in the same boat as I was. Wife decided to end the marriage after dangling a carrot of possible reconciliation. Been there, done that. I also bought my ex out of the house. I can't say that was the best decision that I ever made. Yes, I loved the house, but after she was gone, the house was haunted with all the memories we had created and the lingering hopes and dreams we had discussed.
I ended up selling the house and buying a new house to become my home. A fresh start for a new life. For me, it was good to break the knot that connected me to my children's mother. I was sad to see it go, but the new location ended up being a great place for my kids, with a bunch of friends in the neighborhood. Plus a bunch of new neighbors that knew nothing about what happened and I could move on.
You are in a tough spot, but as long as things are amiable, hopefully you and your stbx can work through things. Mine had a pretty good head and at least wanted to work together to still raise our kids. It was a bitter pill to swallow for a while, but I put on my game face. Several years later, the kids are doing great and going off to college. Life has moved on as well personally.
