Am I wrong to be hurt

On Friday I was sexually assaulted at a party. It wasn’t rape but while half way blacked out a girl fondled my body inappropriately without my consent. I have had conflicting emotions about the situation and still have a hard time knowing how to understand the way I feel. I asked my boyfriend to not just tell his friends what happened. I didn’t share my reasoning but it was because I don’t want to people to see me and know what happened and pity me or whatever. Just a few minutes ago I woke up in the middle of a nap to hear my boyfriend talking on discord with his friend. I heard him say “don’t tell ___ that I told you this but she was sexually assualted at a party” he didn’t tell his friend what had happened but mentioned that it was a female.

I am not sure what the context of their conversation had been but it seemed that the friend he was talking to was implying that he had also been assualted before. I am not sure if my boyfriend brought up what happened to me so that the guy felt like he could be related to or if my boyfriend just wanted to talk to somebody about it but I am hurt that my boyfriend said so boldly to not tell me about it. If my boyfriend was going to go and tell people then I would appreciate it if he didn’t act so secretly and would let me know who he told. I assume that he is not planning on telling me that he told anyone. It just makes me begin to worry that he will tell others as well. Do I have a right to feel hurt by what he said and does anyone have any idea what I should do? How should I react?

Should I give him time to tell me about it and if he doesn’t tell then I tell him what I heard?
