I need help. I need to figure out a way to get my sister in-law to break up with her total loser live-in boyfriend. The guy is a total cancer. He hasn't worked in over 2 years (she supports him on a very modest income). He has 3 kids from previous marriages, he doesn't pay any support. He has no friends. He is verbally abusive to her. All of her friends have abandoned her, saying they refuse to be a part of her life if he's around. He last got a job as a janitor but immediately quit because "it was too hard" on his knees. They live somewhat close and this is all my wife and her parents talk about. My wife is going crazy at the thought of little sister with such a piece of shit. She drags me into everything. Holidays are awkward as fuck. I'm forced into these family gatherings. How can I break them up? Should I recommend we go nuclear and have an intervention to lay it all out?
