I've just discovered that a close family member of mine has given their partner a black eye twice when drunk. When not drunk, this family member has never behaved at all inappropriately, and is devastated by their drunken actions. I think the family member has a problem with alcohol and I'm really worried for the partner and also for the family member (shitty as their actions have been). My question is, if the family member can give up alcohol, properly and for good, should their partner still leave them, or is there hope? I'm at a loss about how to offer support.
TIA
