I feel for u and being with someone who has a drinking problem while sucks is fixable.There are drugs she can take for sex drive.I would get her to go to church with u and as ridiculous as it may sound I would join a health club together and take group fitness classes together.I promise she will feel better about herself and it would up her sex drive.Most of all the classes are for all fitness levels and she can sweat that shz out.I grew up w 3 women( dad killed by drink driver when I was 5) and I have 6 females at home 62,39,6,2,3mo,3mo and used to manage ladies only health clubs for years and train their best managers.Communication is so HUGE..being sweet,patient and understanding.BTW,I'm heterosexual but have many women friends.If she is the type that shakes in morn for alcohol u have to get her checked in.Help her get a hobby..gardening ,cooking,fitness and church will help.I wouldn't abandon her unless she was scrrwing someone else and she isn't..AA meetings will allow her to talk to someone else.This is very serious and u have to be proactive and help her IMO.I've made huge sacrifices for my life so my sis can have one with her kids. It's frustrating but it also feels good being selfless hero.Wish u all the best.
