I DON'T KNOW WHAT TO DO ANYMORE!

So yesterday, Candy had been drinking again and started crying and saying that she is weak and that she loves me and what an idiot I was for pushing her away when we should have talked. I made her throw away the rest of the bottle of Gin down the kitchen sink. And I thought all our problems were over, but oh boy was I wrong. She disappeared into the bathroom to sing and listen to music while I watched TV, and then I heard a lot of banging about and crying from her. I wheeled myself over and she tells me that "David's" dad is very ill and could be dying. So she's upset and crying her eyes out and theres nothing I could do. Later on, she goes for a walk outside and she still appears and acts drunk. when she got home, she goes to lay down in bed and starts to cry again, I try to comfort her but she again decides to go out for a walk. when she gets back, she is very closed off and lays down again until she gets a phone call from her Australian friend and they laugh and giggle and chat for over an hour. She then goes back to bed and starts crying again. the time is then 04:30 and the both of us had been up since 9am, I conked out and went to sleep, listening to her cry. This morning, she was very delicate and not very chatty with me. I do believe that there was more then one bottle of gin and she has lied to me. I don't know what to do anymore.
