Me and my partner have totally different recollections regarding an incident that turned violent. We were arguing verbally and (in my memory) he pushed me down onto the bed very harshly and held me down. I have bruises on my upper/lower arms from grabbing. He says that what I say happened didn't and calls me a liar and calls me sick in the head. He is SO convincing and certain it makes me doubt myself. I have apologized for my behaviour that day, not blaming anyone else, and promised to work on myself.
He has said nothing, only that everything that day was me alone. While I agree we were verbally arguing I did nothing physical toward him (and he's twice my size), yet he says he was defending himself from me and that's how I got bruised; that I attacked him. He has no bruises or anything. I feel so confused. He stares me straight into the face and tells me that. It makes me question my reality. He also said I have bruises cause I just bruise easily. There's never been physical violence between us before. Any advice?
