I had to hospitalize my boyfriend - can you help?

I'm 27F, he is 31M. We were engaged a few years back, and broke up for awhile and were working on making our way back to each other when his psychotic break happened.

Unbeknownst to me, he'd been doing a ton of drugs [such drugs, much bad], including oxy 30s, ritalin, ambiens, mushrooms, whatever. He decided to cold turkey detox off of them and ended up triggering a [latent?] psychotic break.

He got rapidly obsessed with the GTA:V Chiliad mystery, and he started making connections in real life. He fell down the rabbit hole very quickly - paranoid delusions of people stalking him, trying to screw him over, watch his every move, grandiose delusions of thinking he figured out this puzzle and the fame and money he was going to get from it, religious delusions of thinking he is the son of god... it's basically everything you can think of regarding psychosis that you hear about.

Throughout this process, he reached out to me and made me help him - he kept calling me the one who was keeping him tied to sanity and reality, the one keeping him grounded, the one keeping him from getting in trouble. We are reconciling, so I was of course there with him through the entire process. I am familiar with psychology and things like this, so I knew he was going to need some serious help and tried to convince his mother to help me to no avail - she was in denial/a drug addict herself.

Basically it culminated in him telling me that he had to kill himself to solve this puzzle. At this point I realized I needed to get him help so I called his cousin [who I had talked to earlier and he had found a place to take him], we convinced him to go. The entire time he was convinced he would die - then he had a manic mood flip as soon as we got there.

Longer story short, he's been in there since Friday. He was pink-slipped, being held involuntarily, and has it in his head that it is my fault that he's in there as I was the one who took him. He was refusing meds up until I went to go see him in person and convinced him that he wasn't going to die if he took them. I've basically devoted my life to the thing now.

He is on lithium and risperdal, day 5 - he has been diagnosed bipolar I and deeply psychotic up until today. Today he decided he was going to sign in voluntarily and take treatment voluntarily, which they tell me is a good sign. He still thinks I can get him out and he's got some disordered thinking going on still, so I know he's still very sick. But he's the calmest he's been in a week, and starting to sound like his normal self again.

Have anyone of you been through this before? I have some questions.

1. What can I do to help him? I have been very sensitive and gentle, loving and encouraging to work in therapy, take meds, etc. I call him every day, drop off letters [facility is close to my house], have visited him every time they allowed me to [his family has not, but they are taking guardianship of him at this time]. What else can I do?
2. What will he remember of this episode? Will he remember what happened, the love he expressed to me, the delusions? Will he be depressed after? How can I help him at that point?
3. A big worry of mine is that he wanted to try and make things work with me because of the delusions. I know it's selfish, but I can't help myself. Can anyone shed any light on that?

Anyway - sorry for the epic post. It's been an insane few days, and I've basically done nothing but think about this/research/etc. I could use any help you're willing to give me. I thank you in advance.

My husband used to visit me every day in hospital. He would shower after work, put on fresh clothes and perhaps bring a rose or chocolates or something. If I had leave off the ward he would take me out for ice-cream or dinner or something.

The thing is just being there.

My husband (we've been married four years) sometimes wonders if I just accepted him because I was manic. This is not true. I really love him.

In your case it sounds like your bf has been through a lot, but it seems like he identifies you as the main person in his life. From the way you describe it it sounds like he loves you. But give it some time. It's not over yet.

Just being there.
