Oh my. Sounds like he is really hurting...really lost. How sad that what he needs is serious counseling and maybe meds, but instead, like many of our spouses, he is running. I'll think good thoughts for him, but also think them for you.
This space from him will help you heal and gain some perspective. And there is no need to do this alone. I just got a reference today for a counselor and I would be lost without this board. HUGS!
