The relationship between brother and sister is a complicated one at the best of times. But when it comes to in-laws — what started off as complicated can become downright tumultuous.

Below is a list of 15 stories of brothers and sisters-in-law that are truly awful. As bad as you might think you've got it, trust me when I say it can get a whole lot worse.

How am I the bad guy?

After Buzzfeed Community member violinfemmes's sister-in-law decided to go on a racist social media rant — she made the hard decision to cut her out of her life.

You know I want ya; I know you want me

"My sister-in-law started romantically, and creepily, stalking my uncle. Gross, right?

BuzzFeed Community member allisonq4df71232a recalled how she once referred to her brother-in-law as her own brother while they were out drinking. Later on, she got a text from him explaining how she couldn't call him that because she hadn't earned the right.

Dealing with constant negativity is too much to bear.

Isn't that a good thing?
