Hi,
I know how heart breaking this may be for you, and I am sorry for your pain...
I see one problem amongst others, that will happen if your girlfriend continues to drink...Soon, she may not be a closet drinker, and get sloushed right in front of you, which could bring about other painful issues.
You can continue to be a good example and keep your addiction in check...As others have said here, Alanon is a great group to be involved with...Lots of great advise here...above...:ghug
# one, keep yourself healthy and free from active addiction...If this cannot be you may need to evaluate this relationship...Is it worth hanging unto?
