Is this considered rape?

I'm super uncomfortable posting about this because I know there is going to be a lot of hate.. but one, I need a place to vent, and two I need advice. So I was dating a guy and we moved in together. A lot of things ended up happening in our relationship that ultimately ended things between us. Like him cheating and getting drunk constantly. Me always having an attitude and getting angry with him( I didn't know why until after we broke up). So about a week after we broke up, me and a friend were watching a movie, and something triggered my memories. I started to have flashbacks of me and him drinking two different nights. He was an anal guy and I had never done anal. The very first time it happened, I told him no and continued to tell him no to anal. We were already having sex at that point but he wanted to do anal so it ended up happening and I remember just laying there. The second time I fought a little more but ultimately ended up losing and he got his way. I also remembered a time where he told me he was having sex with a girl and she passed out because she was drunk and he finished anyway. There was another time he was mad while we were having sex and he choked me so hard I almost passed out. I feel like I blocked all of these things out because I couldn't mentally handle it. Why it came back to me I dont know. It makes me feel like I'm crazy, and I don't say anything to anyone except my best friend because she believe me and is a rape victim as well, because I know nobody would believe me because I was dating him after it happened. Can someone please talk to me about this? I have such a hard time living with myself and downing myself because of it.
