First I want to start by staying you're very brave for doing what you needed to do. I know that's not easy... I made this same decision earlier in February. I moved out for 10-days until my AH agreed to get sober. He's on day 29, I don't know how it will go moving forward, but having that time apart and away from the chaos was the best thing I've done for myself and our marriage in over 22 years.
Keep coming here for support and as other posters suggested, Al Anon helps. I've been going for a month now and I've learned ways to communicate with my AH that are much more helpful than what I was doing before.
We also don't have children, we tried, and although there have been times I've been sad about it. It's nice knowing I can walk away, or he can, we don't have children in the mix. I love the idea of freezing eggs, thanks for suggesting that dandelion.
Hang in there, take care of yourself, you're not alone! I'm here anytime, you need someone to chat with.
