Good for you! I'm glad you're feeling positive. Happy (belated now I believe?) birthday!
"She's worried that she might end up losing me. Honestly, there's a part of that that thinks "Good! You need to worry about that because it's a reality and a possible consequence of your behaviors."
I think a lot of us must have felt this, I sure have at least anyway. Like I always just want my mum to wake up one day and realise she is hurting me and want to stop. It's a shame it isn't just that easy isn't it! Actually, I'm sure a lot of the time they DO know it hurts us but the alcoholism just takes over.
Taking things slow IS the healthy way to deal with things.
I hope your son is feeling better soon!
