My sister dated a deadbeat dad who owed back child support in the amount of 15-20K, could never hold down a job because [insert some conspiracy theory here], and who had a history of domestic abuse against his ex-fiance and mother of his child. He was also a complete nutjob who was an avid follower of Alex Jones, got my sister drinking that Kool-Aid for a long while, and was just an all around scum of the sewers kind of guy. They were not-so-secretly engaged for a brief period of time because my sister knew that we all hated him, and my parents were especially antagonistic. He was explicitly forbidden from ever entering their home.

They broke up suddenly, for reasons my parents never learned but she told me, though it doesn't really make sense to me. Something like, she wanted to move to a certain state, he said something along the lines of "actually, no." And then he just left for that state anyway to re-connect with his child. Something else definitely happened.

About a year ago she was visiting me and she got a phone call that left her upset. She told me that he had killed himself. She was a little upset, but I think our evening plans distracted her well enough. Later she said she was upset because her first thought was "good, that's one less monster in the world" and she thought that made her a horrible person. She never elaborated on why she thought he was a monster. She swears up and down that he never hit or abused her in any way, but my mom and I have strongly suspected for years that's a lie. And she said something to a friend when I was visiting her a few months ago that makes me think she was definitely abused.
