My (intp, female) boyfriend (infp, male) has a video recording of me singing and jamming along with strangers on a night when we were out for a date. It was a good day. That song was a love song and it was dedicated to him.

I feel kind of enthralled that he had recorded it (although I felt mildly put off because I dont like having videos of me taken, without my permission. Didnt press anymore because I know he's sentimental and he likes to save these kinds of things). Earlier this day he brought it up and he said he wanted to flex it on social media. I feel uneasy with this because:

a) I don't like having my soft side seen by people I know who aren't close friends/my boyfriend b) His lady friends had a bad opinion on me (which happened when he vented to them one sidedly about a problem that involved me shitposting about my ex, in which case I wasn't even serious of) and I don't want them to see that. c) I'm a private person and I don't like drawing attention to myself. I also don't think it's necessary. d) I also think relationship posts are cringy on social media. Public display of overly physical affection in general is cringy to me. I'm also usually a idgaf type of person but emotional things like this just aren't my thing. e) I'm not too confident with my voice and I don't want people who know me to hear it.

I asked him what's the purpose of that. He says it's because he wants to make an appreciation post, to which I told him that I already feel appreciated enough, no need to draw more attention. Then he admitted he wanted to flex me, which I am not keen of, as I have mild trauma about exes using me for clout. I told him I am not too settled with the idea and I sensed dismay so I told him that if he wants to post that video, he can go ahead.

Now he's sulking and he's saying he doesn't want to do it anymore because he feels as if I'm just being forced (which, I am not, I am just a bit uneasy on the idea but I'm not overly against it due to me wanting his happiness)

I assured him that if he wants to do it, he can. Even so, he says he's not in the mood anymore and the conversation between us has turned dull. I tried to reason but he's just dismissive.

I'm a bit worried he might overthink things. I'm also a bit relieved that he is discouraged to post/flex. I may be the asshole for telling him off like that because I felt like I cut off his happiness for my comfort.

Am I in the wrong? I'd like to know how.
