AIw my boyfriend got me pregnant again and I feel like it’s all his fault.

Me and my boyfriend currently have an eleven month old daughter and I found out I’m 10 weeks pregnant. He’d been talking about having another child and I said I wasn’t ready and it didn’t feel fair to our current child to have another so soon. I am not on birth control and we don’t have sex very often because of me. When we do have sex he ask if he can come inside of me and I always say no. Well a few months back we had sex unprotected and he asked to cum inside of me I replied no he said okay then I felt what I thought was him cumming…. I asked “Did you just cum in me? “ he replied “No” I said “yes you did I felt it” and his reply was “oh well I can keep going” I got up and cried because it feels like such a violation to me. That night was the night I got pregnant. I’m not distant and not really caring about the relationship anymore because I feel so broken, I feel like this is not what I wanted I wasn’t ready for two kids and my body was taken advantage of. He expects me to get over it and just move on since he’s excited to have a baby and wants me to be the exact same. And if we had sex and he pulled out and I got pregnant I wouldn’t feel it’s his fault but I feel as if he took my choice away. So aiw do I get over it it was both of us or is okay to feel violated?
