I don’t have anything to add, except....get yourself sober and YOU escape to disneyland too.
I was the drunk, but running off to Disneyland with my kids during sober times was my move, not his.
Take care of you.
Get to class, get sober, treat yourself gently, and don’t worry about what he thinks, you’ll never know the complete story of everything he’s feeling, so clean up your side of the fence no matter what he’s feeling....and that will help you best.
