Damn, that's a tough spot to be in, duchie.
Some fighters can smell fear and intimidation in others and it only makes them angry.
A lot of the times they appreciate honesty.
Not saying some aren't testosterone-rich dicks, but most are just average guys who happen to be able to fight well.
But head trauma, mixed with loss of being allowed to work, and alcohol abuse is a sleeping firestorm waiting for a spark.
Not sure how I'd handle that one.
I'd just keep it cordial, keep true to yourself when dealing with him, and find things that will keep you busy and away from the guy as much as possible.
You've got enough on your plate right now keeping your own stuff together as you try to move forward.
And hope that word doesn't get to him that the wife's been "talking behind his back".
Oi vey is right.
