We moved 1,000 miles away from all of our friends and family because he "needed a fresh start"...and we moved for his job. 18 months later he had added a new drug (common in that locale), escalated his abusive behaviors, had an affair, and ultimately abandoned me and the kids. The only thing that changed with the move was that I was dreadfully alone. The kids were too, it was so horrible. The kids and I moved back, but it was the roughest time of their lives, and I wish I could have that back. In hindsight, I think...fix first, move later. My X wasn't even that bad when we first moved, but he was definitely trying to solve a problem. I think the move ended up escalating it.
I'm so sorry for what you're going through.
