If you haven't been around her physically for some time, sounds like that's the best plan to stick with. Drinking or not, pointing a gun is inexcusable and dangerous. I think it's important to set boundaries and not cave to the manipulation alcoholics are so good at. My parents always forgave my brother and listened to every excuse...so today he is 50 and still addicted. They are in their early 80's and still stuck. You don't want that life, for you OR your daughter.
