Oh, Coffeelover. I'm so sorry that you and your kids had to deal with this. What an awful thing, to open the suitcase and find the little bottles of vodka, then deal with the threats of suicide, then the police and EMs.
You do not have to decide anything right now. Take the time you need to consider everything, but first please try to get some rest and take care of you. Snuggle your dear little ones and let them know you love them.
Please do keep in mind that just because he's been a stay at home dad, it doesn't mean he's not capable of finding some way to support himself, if he really wants to. If he doesn't want to, that's not your fault either.
Big, big
