Welcome Blue.
It might be that your partner won't be able to 'get it', and the trust will just need to be earned back over time. TIME - Things I Must Earn. Doesn't sit well with the average instant-relief seeking alcoholic, but we can learn to accept and live life on those kind of terms. That's what recovery is about.
It's worth finding out about support groups locally so when you come home you can get straight into that recovery work. A detox doesn't reset our broken off-switch, so it's something we need to keep working on, like we need to eat, sleep, and go to the bathroom. Otherwise we will, if we're lucky, get a rotten quality of sobriety, or if less lucky, and up drinking again.
If you contact your local area AA they will likely be able to send someone (same gender) to come visit you for a chat in hospital if that woukd be helpful.
