My (28F) bf (33M) did something to me sexually that I did not consent to and he told me not to ever do it to him, so why did he do it to me?

I’m stuck in a debacle that I don’t even know how to get out of. I don’t even know how to introduce it other than getting straight into it. My bf (let’s call him Jack) and I were having sex when he asked me if I wanted to try a certain sex act. I said no, we both dropped it, and went about our business. <br><br>For context, Jack and I have been together for about two years and the communication is great, so does the communication.<br><br>About a week or so later, Jack and I got into a heated argument about something else (i honestly don’t even remember) and in the heat of the moment, he did the sex act that he asked me to try a while back. My reaction was that of utter shock at first, then I was upset. <br><br>I haven’t been able to let go of that moment and it’s been really affecting our relationship and my mental health. It feels like I lost trust in him and his care for me because he did something to me that I didn’t consent to. <br><br>I told him multiple times that what he did bothered me a lot and that he disrespected me. He kept apologizing and promising it would never happen again and that he’s really sorry but he just wasn’t in his right mind during that moment, which was hard for me to believe since when he did it, he seemed to be very aware and very much in his right mind. <br><br>Jack asked what he could do to make it up to me and I told him to get therapy. Then I asked if he’d be okay with me getting therapy and he said yes but then retracted his support later on and said he doesn’t like the idea. <br><br>We’re at a crossroads and I don’t know what else to do. TL;DR: My bf did something to me sexually that I did not consent to, even after I told him no after he asked me to try it, so I’m feeling very violated and disrespected and I don’t know what to do to move past this moment.
