Welcome to SR, Donna.
Congratulations on taking a few steps forward in your recovery.
I put the word recovery on your feet because you'll find after enough reading that getting him healthy and not able to leave him and him and him and him, has nothing to do with you.
You're not as stuck as you may think and what I mean by that, is you have ways to reduce the impact your AW is having on you. You can take action to improve your life until you're in a position to make bigger/harder decisions about your future.
Keep on reading and keep on posting. You have a massive support team right here and yes, we've all seen something similar and different.
