Hello BadChoices,
Welcome. This forum is a wonderful means of support. You will receive strong words of advice and useful information. Be open to the advice and decide for yourself what path is right for you.
What I found helpful is reading what others experience. Sometimes through reading their story you feel less alone in your struggles and/or appreciative of their tranparency. Someone once shared advice they received from a theraphist that stuck with me. The advice was to be willing to accept a person for who they are now, not who they could potentially become. It really hit home for me because beyond the alcoholic we are in relationship with we ocassionally experience them sober (the potential), on which we hang our hopes. Do you accept where your BF is now? Make your decision out of love for self first.
