Oh what a painful time for you.
I think you did the right thing.
I can't say I've ever been in exactly that situation but I certainly remember how overwhelmed, anxious, and sick I felt when I finally made the decision to leave my husband.
Please know that you will be OK. The details get worked out one by one, when they need to be. You are meeting with the lawyer tomorrow. That is the next right thing. Tomorrow you can figure out the next step..and so it goes.
Not communicating with him is a gift. Talking the endless circles of an alcoholic relationship did nothing but confuse me (understatement of the year). Take some time to take a breath, take a break from his quacking, and find some clarity. Keep reading here, find an al anon meeting, get some sleep, play with your kids, etc. I can't remember if you have read the book 'Co dependent No More' but I found it very helpful.
