Lost
I do feel for you. I know how it feels to have no job and worry about housing, cash and kids if I leave. Because I used to feel like this.
What happened to me was that I saw a solicitor in July and threatened it. A false fresh start ensued, but it didnt last. Then in early October I made plans to leave, and moved out of the bedroom.
What was different that time is that family knew, and he knew they did, and I completely withdrew from him not the other way around. An appointment at Relate came up, which we had sought in August (we live in a remote place for services), so we still went. I thought that at least we could get an amicable split, or less acrimonious anyway.
In my case, h really changed and started to make an effort once this happened. In a room with a male counsellor, he cut all the crap and prevarication and self justification.
I am not telling you this because I think this may happen to you. I note you have already been to counselling. I think the message I am putting forward is that I got change in my relationship, as I drew a line finally over what I could live with, and critically, I meant it. I really would have left, no question. He understood and believed this, and it is that which made the difference.
Either way, how could I lave lost? I felt quite exhilarated actually, taking back control of my life. If things hadnt worked out, at least I knew for sure that things would never have changed, and I already knew finally that I couldnt tolerate what I was getting. And that all those excuses for withdrawing emotionally which he used to give me were just that, excuses.
