Hi there Deelilah,
I'm a late comer in posting on your thread. However, I have read everything you and the other posters have said. Just want to say you are doing the right thing. Your AH might change or he might not, but you should look after YOU and do what is best for you. The depression thing you mentioned your AH mentions just made me laugh. I call that total BS! My now late AH used to say he was depressed and filled with anxiety, went into counseling and was prescribed antidepressants after persistently asking for it. Thing was the depression was a symptom oh him USING, which of course I didn't know because he lied big time. What he should have done and needed to do was to deal with his addiction, just that he didn't want to. It was easier to blame the depression for being the problem. Could be the same with your AH. Watch out.
Sending you hugs,
SoDev
