The are only a few things I wanna touch on just because of your H's poor mental state and the ride you've been forced on with him.
First the alcoholism can be contributing heavily to the depression instead of vice versa. Alcohol is a depressant. If he can't get sober long enough to remember what good emotions feel like it's a really crappy downward spiral.
Next the GI issues while they can be related to poor mental health can also be from the heavy drinking taking a toll.
Just keep a close eye on that if you can. If not you may want to warn him and he can take it as he likes.
Next this:

I don't know what the deal is where you're at but you might wanna look into it. In the States we have the 51/50 option. In every state. He claims he's going to hurt himself you call the cops, the cops and an ambulance show up. They go on a 72 hour hold. Can't check themselves out. Here, and I say that because I don't know by you, I had to deal with this with official ex not my might be ex current H, and at first I was like you panic stricken and not wanting to upset him or make things worse. After very little digging I realized that I had 51/50 at my disposal. If he would threaten it I would say, you have a few choices here, don't say things you don't mean to scare me, I can call your mom the nurse and you can tell her what you just said to me in the state you're in (which was typically out of his mind drunk and high), or I can call the cops right now, and they'll be happy to escort you to the emergency mental health care you clearly need. He'd immediately back pedal, but I also knew it was an attention grab. If you're unsure, I'd play it safe for a little while.

This....god this. Mental health, booze or not. All these crazy WAH/WH's have the same shtick. H keeps talking to me about this marathon and his trip and my trip and then after, like he's just staying forever and then casually drops his move into conversation just to remind me he's going and I can't stop him, even though not once have I ever even tried...Ugh.
