Hi ROMB,
Just wanted to say that I too know how you are feeling.
My H is going through a return to a cold and irritable stage that I haven't seen since around BD.
It's very disheartening after all the work we've put in, but it's good to see feedback from others (IS, JB,lc4) that there is still a chance for our H's being involved/ invested.

Please keep us posted as to how you are doing with this.
I'm trying to be more detached and quiet around my H, but it hasn't produced any results yet (although I'm only really a week in to the cold and irritable treatment from him).

I'll be thinking of you,
NLW.
