There’s a reason why someone becomes our “ex”—because only we know how they actually are, even if they charm our family. Now imagine, this ex ends up marrying someone within your own family. That would definitely make things awkward, wouldn’t it?
That’s what happened with Reddit user Standard_Raccoon8402, whose ex married her brother, yet constantly brought up things about their relationship, making the whole family feel awkward. Later, he became so toxic that the original poster (OP) tried to talk to her brother about it, but he thought that she was doing it out of jealousy!
