She will continue drinking, her mom is a big drinker still and used to be a wake and bake drinker. She (my ex) was always the one in the relationship who was the "I don't have a problem" half. I sent her and her family a christmas card but didn't hear anything. I'm convinced that I am being made into the bad guy by her mom, which hurts as I'm a kind person and I believe I did the right thing for both of us, at least she's not doing mounds of coke as well now.
Me and my old man are very close, he has helped me a great deal. Thank you both for your advice it has really given me a great insight! I do take full responsibility for what passes my lips, it's just that the situation is made much harder when you have someone else doing it right in your face and right under your nose (metaphorically). Thank you both so much @pelican and @deeter Happy Holidays !
