Am I dramatic for caring about this?

I’m 19F with 22M and we’ve been in a relationship for 3-4 months now.

I’m usually pretty lenient within what I expect I. A relationship. I don’t mind splitting payments, him having friends that are girls, following friends that are girls, not having his location, making time for his friends instead of me sometimes. I also don’t really feel insecure around other girls when I’m with him I’m public. I don’t think those things are an issue personally

But there’s this one girl he follows that he doesn’t know, doesn’t follow him back, has around 500 followers, is around his age and only posts lip sync reels/thirst traps. She’s beautiful and of course I don’t blame her for any of it. When I asked him about it he said that it’s because she kept coming up on his fyp and had cool music taste so he followed her.

She is so beautiful, has “good” music taste and he’s liked almost every reel. Her comments just have guys flirting with her (all pretty respectful) but yeah her thirst traps certainly bring male attention. One guy made a comment

One guy commented “here from the comment you made a few days ago saying hmu if you’re 5,5” which worries me even more as my man is around that height (maybe 5,6) so she’s obvs in to guys like him and he knows it now. What if he’s been in her dms? Or lusting over her?

Is this something worth me worrying about?

Tl;dr boyfriend liking other girls posts that he doesn’t know and follows her. Not sure if I’m being dramatic
