Oh littlesez I'm so sorry
Massive {{hugs}}
I don't think it's impossible that he will sort himself out. He has admitted out loud to having a problem, that is a huge step, and I believe, the hardest one.
When I was 22/23, my best friend (same age) told me she was an alcoholic. She didn't drink any more than I did, we were out together nearly every night and tbh, yes, our lives at the time revolved around being out drinking (not much else to do really).
She worked up the road from my pub and used to come in for lunch so we'd even both have a drink then.
The difference between us was the attitude to the alcohol. Like I said, we were mostly always matched glass for glass, but she viewed it as a necessity(sp?) and I viewed it as a choice. I didn't have to have a glass of wine, I could have just as easily had a lemonade, but I didn't. She didn't feel she had that choice.
We don't talk anymore but as far as I know, she has been sober for over 5 years. (The reason we don't talk is because she is a selfish, heartless person who showed signs of resentment to my PFB and we no longer had anything in common)
It is completely your choice on what happens now regarding your OH, but if he has admitted to having a problem, that is a good sign.
I understand you not wanting Izzy around this behaviour if this is what you experienced as a child, so I don't think you are being unreasonable, but i do think you both should sit down and talk about this.
Just try to be completely honest with each other.
Hopefully your OH will want to seek proper help for his addiction (which I do believe is a disease, not a choice) and once that is under way you guys can try to work towards getting your relationship back on track.
Just take it slowly. Find out where his nearest AA meetings are, or rather let him do it, I think it's very important that he has full control of his recovery, very important. He can only move at a pace he is happy with.
I take it he is aware of your fathers drink problems? What I'd suggest is that you both sit down (he has to be sober) and you tell him some childhood memories of your father and his drinking and tell him that you are not prepared for history to repeat itselfr and for your dd to go through the same thing and have this conversation with her OH in 30 years time.
Tell him that you love him (if that is the case?)
tell him you are willing to help and support him in any way you can, but tell him how important it is that he stops the drinking and seeks help.
tell him he can come round for Izzy's bath every night as long as he is sober and that you'd be willing to work on your relationship after he has started a course of recovery. If he starts AA, he will need support.
Obviously I don't know the full history and i don't know what you want, so feel free to ignore the above, only you can decide what happens from here.
Did you write down your feelings and thoughts last night like dinky suggeszted?
I find everything easier to understand when it is down on paper.
