I am sooo sorry. Please.... get some help for yourself. All the posts above are right on...he did you a favor...
"When the questions got tough he fell back on addiction, not knowing anything, living in limbo, hating himself.."
This is quacking.. quack quack... he'll say anything to manipulate you. look at his ACTIONS. They are of someone that wants to get high, and rest/crash period.
Again I'm sorry but this CAN get worse. When he gets desperate.. this CAN and WILL get physical. Please change your locks, get an alarm system, or MOVE. I wasn't ready to let go of my husband but i at least moved, got a PO box, and will never let him know where I live, no matter how good he's doing.. my home is a peaceful sanctuary, as yours should be. There's no banging at 4 in the morning. Please take the advice and go to AL Anon and get a new therapist just for yourself.
This is NOTHING NEW.. it's been going on for 4 YEARS. Please get some help. You are in my prayers.
