I will tell you something, don't take his words at heart.
if he was really drunk he can very well said things he did not mean or exagerate little trues and make them see as a big problem, I have two examples for you:
N1- I was really drunk and I wanted to confess my eternal love to my friend's wife, thank god 2 other friends stop me and it never happened.
The next day I did not remebered that I tried to do that, but after both of my friends told me, I had some flash backs, the true is that I knew my friend's wife for many years and I had a crush on her when we were teenegers but by no means when this happened I was in love with her and I had never thought she was the love of my life (I really don't know where that came from).
N2- I was really drunk again, and I told a friend that he was not my friend anymore, that I have always been loyal with him but when I needed him, he failed me, and I didn't trust him anymore, and I didn't need a friend like that in my life.
Why I told him this?, because he couldn't take me to the airport one time, and I had taken him in two previous ocassions, I mean, I was kind of pissed but I will never cut a friendship or put that drama just because he could not reciprocate a favor.
so maybe there is some true in what he said but not real feelings.
I mean, maybe he does really think that if you divorce you will take the kids to Louisiana, but that does not mean he wants divorce or is thinking in divorcing you, is just something he thinks you will do if you both got separated.
also drunks can be jerks if you want to force them to do something against their will, he could very easy just blurp something to hurt you for you to leave him alone.
