Ann, for what it's worth? I think you showed considerable restraint. I thought the dent came from hitting his hard head!
dear LovesBulldogs, please get out while you can. Don't stay. It's not worth it. I say this as an alcoholic. It's a vicious, hateful disease. It sounds like he's firmly in its grip. best thing you can do is leave him. It might be enough shock to get him to AA or make a serious attempt to get sober. don't use the threat and be prepared to stay gone when you leave. make sure that's what you want and make it permanent.
please know I give this advice with love and as for something for you to consider.
love from Lenina
