Hi again Dansemacabre1971, glad you're continuing to reach out here. Your situation sounds stressful because it isn't "just" that he's living in the garage, it's also that his employment choices are intertwined with your life -- and your kids' lives.
I wonder if dividing your situation into two parts might be a way to tackle things?
One part is the relational side. It's sad and frustrating that he is pushing away and isn't speaking to you or the kids. I think we both know that that isn't something you can control. It's not like "if you just said the perfect words" or "if you just acted the perfect way" he would snap out of it. So maybe this first part -- the relational stuff -- can be allowed to be sad and frustrating, and yet also a place to have some
radical acceptance.
The other part is the practical, logistical side (money, jobs, finances, etc). It could be a lot to try to work on both the relational and the logistical parts at once. That's a lot of energy. So you can think about if you want to just focus on practical problem-solving part and get that squared away first, and then think about having time and energy to look at the relational stuff.
What do you think about breaking it down that way?
If it's something you want to try, we're a good group for practical problem solving
