hello kitty-
i'm glad you are staying at your dad's house and have a bit of time to decompress and let your feelings settle. there's really no point in trying to reason with an active alcoholic, as you are discovering. all your very reasonable and logical points are countered with confused foggy thinking. i know, for myself, i second guessed myself for a long, long time.
however, once i made my move and got a bit of space, i grew stronger in my own true rational feelings. i don't think this is really possible while living in the middle of a cyclone. and despite all my xABFs quacking, begging, pleading, threatening to kill himself, all of sudden, i could see it for what it was and held my newly found ground.
it's a journey. you take care of yourself and givelove is right, do something nice for yourself today.
