Like I said, all you can do is sit on the sidelines and watch. Trust me, I've got a great friend who's an incredible woman and mother and is married to a HUGE asswipe. I've disliked the guy since day one. He's loud, rude, drinks too much, has cheated on her, has treated her like sh*t for the last 11 years they've been together and I've sat there just listening to her bitch about him. I tell her a pile of dog sh*t has more character than he does and yet she continues to stay with him. Your friend will either get drug down into his pathetic existence OR she'll pull herself up and move on and leave his loser ass behind.
Let's hope she knows what the right thing to do is. I can't imagine why your friend is still with that guy. Maybe it's for her children.
