I have been pondering your situation, and I here is my opinion - but it's just an opinion, okay?
I don't think you should drop the D. If you had LS in Florida, I'd say go with that, but you don't. Remember how he promised to changed, etc when you filled out the papers last time? And then he came home and nothing changed.
He is scared, and this may be what he needs to actually do something about his own issues, but I don't think he will if you don't follow through.
If you can see that he's making a sincere effort in a couple of months, you could always put the D on hold, but I would really wait a bit to see what happens.
I know this is hard on you, and I know how much you want your family to be together. But there's no point taking back an unhealthy man who will bring you all down to his level.
You can always remarry him if it goes as far as divorce. It does happen!
Lisa, I really want what's best for you. Be strong and listen to your gut - you know better than anyone else what to do.
