Hi, Chelle. (Feels kinda weird to type that
- it's what my family calls me. And I've rarely seen any one else use it.) Welcome to SR. I'd echo what Tuffgirl said. XAH did it all the time the last few years DS and I lived with him, but I wouldn't call it sleeping, I'd definitely call it passing out. I hated it. He'd come to and drink more and then stagger back to the bedroom.
Also just want to say: Unless your mom and sister are living with alcoholics as well, they have absolutely no idea what you're going through. Their advice may be well-intentioned, but only you know what living with alcoholism is doing to you and your kids. IMO, the same rules about making a marriage work do not apply when active addiction or alcoholism is a factor.
Hugs.
