@jack5423,
Ever hear of Tough Love?
The best way to handle this, IMHO, is to let her work this out on her own. Sad to say but once you broke up with her, that was the best time for her to heal.
Instead, she plunged head-long into another relationship, only this time with a control freak. This is hers to work out. Also to get help with the reasons for her alcohol abuse, too.
She's allowed others (you) to be her safety net. She's allowed alcohol to anesthetize her from her self-inflicted pain and her mistakes. The pain is always there after you sober up. She is very needy and dependent. She needs a counselor...not someone to make it all nice-nice and then she goes on keep making the same mistakes again.
"Physician health thyself." For your own sake, get over that relationship and the need to prop her up. I'm not saying ignore her, but you can't help her and she will use you...either consciously or unconsciously.
