OP, you convince yourself that you're iminaging things - I did and you minimise to convince yourself that it's ok to stay. I did that too.
As a passive-ish 21-year old newly-married to an agressive 28 year old, I did nothing when he punched me in the head less than 3 months after our marriage. His reason, he had to do it to get me to talk to him. He used sufficient force that the knuckle of his little finger was permanently pushed back out of alignment with the others.
He insisted on having sex with me, even if I said no, even if it hurt me he said he couldn't feel anything, it didn't hurt him, and continued.
Angry with me for being in a car accident, not my fault, he 'banged' my head in to the headboard of our bed, knowing that I had broken spines in my neck.
When I dared to leave him, he 'helped' me, putting a piece of worktop in the car so, that on doing a u-turn around a roundabout it would have hit my neck at its most vulnerable point.
Please leave, and don't do what I did. I'm so stupid, I stayed 40 years before I left. I could have met someone else who loved me, cherished me and valued me.
