I'm not a bad person and I haven't done anything of note like cheated or been aggressive or hard to live with particularly since I quit drinking over 1.5 years ago so I think it's unfair her asking me to leave.
It's hard to give advice or thoughts based on the small amount of information I know about you. I think you are very smart to consider your child's reaction to a move. She needs to be at the top when considering your options.
My husband left after I quit drinking. Which seems so backwards! I wondered for a long time if he'd just gotten fed up and sobering up had just come too late in the game. But, it seems he liked the drunk me better than the sober me. Maybe she can't handle the new and improved you. I hesitate to say that out as you don't want to drink to please her.
My best to you. If you've been together a while, some heart to heart talking may help.
