I Hate When People Assume Things

I love my parents, but I can't stand when they are being judgemental towards me. MY mom is right about a lot of things, but not this. She assumes that because the way my relationship with my ex ended up that he was hitting/beating on me. That is the furthest from the truth. No matter what I say she doesn't believe Me. Sure he got mad and we had arguments, but he never blew off steam by physically abusing me. He'd punch a hole in the wall before he hits me. My oldest sister some time ago also told me that she believes he hits on me, like where are they getting this from? I admit the dude has anger issues and may even be bipolar, but he never laid a hand on me in an abusive manner.
