What is the worst fight you ever had with your significant other?

The worst fight really I am not sure he cheated I don't trust him he says he is changing the worst fight is me tell him he needs to stop sleeping with her at first he was really mad cause he doesn't want to be push into it. now I think he understand. we had some stupid fights him dropping me off and going out with friends or him spend time with his fling ...

The worst fight I ever had with my ex boyfriend[since I'm single] lol, was that I spend to much time with my family. Which really came out of the blue, and I love my family and their a big part of my life, because without them theirs no me, and he tried to convince me that I shouldn't see my family except on like Sunday's and it just got into a big thing.

The most meaningless fight I had with an ex boyfriend, is we actually fought with each other about fighting with each other. Lol
