I would not close on the house at this time even if you lose the deposit.
He has already been physically abusive and alcoholism is progressive.
You cannot control his drinking, but you can protect yourself from physical
and verbal abuse.
A little shame is better than ending up dead or in the hospital.
I know that sounds harsh, but it is unfortunately the reality of the situation.
He was able to cover his binge drinking when he was on the road without you,
so you haven't anything to be ashamed about anyway.
He is the one who should be ashamed.
You didn't know about this part of him when you got married.
Please educate yourself on both alcoholism and abuse. There are many stickys
at the top of the page. You can't love him well, as much as you want to.
You've already seen he cannot quit with promises. Moving back with him
right now would be very unsafe for you right now. Further financial entaglement
is really out of the question while he is an active alcoholic. Quitting for a couple
of months is still active binging in my book, and I should know since I used to be
a binge alcoholic. He isn't seeking to address the underlying issues nor is he seeking treatment.
Hugs and I'm sorry for what brings you here but you are very welcome.
