I'd suggest you take some time to prioritize your to-do list. Otherwise it can be overwhelming or you could wind up putting your energy into projects that can wait a bit.
Sanity, safety, and security are probably what you want to focus on first. Good that you have your folks to fall back on. Think your husband will be willing to move out so you can rent the house? That's something to discuss with the lawyer.
I don't know how much you've had a chance to read about alcoholism, but forcing people into treatment, when they don't WANT treatment. On the other hand, since he WAS going to AA, maybe on some level he DOES want to get sober. Whether you stay with him or not, you're going to be dealing with him for a long time since you have kids together, and THEY are certainly going to be better off with a sober dad, whether you are together or not.
Just keep putting one foot in front of another, and stick around here--there's some great support to be had.
