I am sorry (((DadFMF))), the decision is really up to you and I think you have been patient in this challenge. I think you are dealing with a person who is very insecure and confused and "hurt" and has been taking some of that out on you. I think you started her on this confusing path and this other guy confused her even more and she is at the point where she is very confused overall about herself. Along with that she is getting a lot of advice that is probably not all that helpful to her or her confused emotions that I think she is trying to escape via the alcohol.

I know you are upset right now, always remember it's best to not act when upset but to step back and take a breather and give yourself space and time to calm down and think logically instead of emotionally.
