DF is father not fiancé. He drinks to excess every day, he doesn’t drink during the day but usually starts around 4pm. He slurs his words and tells rambling stories he’s told many times before but forgotten and gets sneery and nasty to my DM. I know this is horrible but I hate being around him when he’s drinking. I’ve tried to talk to him about how much he drinks but he’s in denial. I don’t know what to do.
