Hi MadelineRose and welcome, sorry for what has brought you here.
I’m betting that there was a time when you couldn’t fathom life without booze in it either and look at you today, 3 years without it!!! That is fantastic. Keep up the good work.
I think you did the most healthiest thing you could possible do was to leave that crazy situation and into the arms of a loving family. Now it’s time to work on staying gone and not going back because you already know what’s back there and it certainly doesn’t look appeasing or promising.
Keep posting, keep reading, go hit up some meetings, Al-anon or AA and try and reach inward for that same strength and courage that has helped you overcome the alcohol. It’s not worth jeopardizing your own sobriety to hang onto someone who doesn’t respect that or you and is showing you they are not interested in giving up the booze/drugs.
