He constantly talked over me, and never listened when I did get the chance to speak. One of his favourite things to say was 'mememememe, that's all I hear when you speak', then get huffy when I told him that he was being rude, as it was 'only a joke' and I needed to get over myself.
He belittled me in front of people constantly, and if I dared stand up for myself I was told I was being 'snotty' and ruining everyone else's good time. Ditto general sexist jokes and comments.
He, in the entire relationship, never met any of my friends, or showed any interest in them at all; in fact I don't think he ever knew the name of my best friend. I lost contact with a lot of people because I stupidly put him first. He basically refused to acknowledge that I had a life and interests outside of time I spent with him.
He was always making decisions for me, and didn't trust me to do anything. Holidays were a good example of this; I never got a say in where we went or how much money I was expected to pay, and he didn't deem me capable of booking anything in case I got it wrong.
He was the personification of mansplaining, once very carefully explaining to me how a map works, and having a massive sulking fit when I firmly told him that I am well aware, thanks.
Expected me to wait on him hand and foot when his mummy wasn't around (we both lived with parents at the time).
This all happened within the first three months, btw. Stayed with him for eighteen years...
