My boyfriend who struggles with insecurity.

A few months ago, I entered a relationship with my boyfriend, and recently he has become increasingly insecure about my Instagram posts. He wants me to delete all of them because he thinks I look too attractive. I’m not revealing anything too provocative—just showing off my curvy body a little. Meanwhile, he’s posting what can only be described as his hottest pictures, with most of them being shirtless, and there aren’t many where he’s actually wearing clothes! He follows every girl on Instagram, and when I asked him about it, he said it was good for his reach. I requested that he stop, but he refused, explaining that he’s been doing this since he was single. I pointed out that he’s no longer single and that this behavior hurts me, but he’s focused on becoming an influencer and insists on following back every girl. I feel like I’m not his type since I have a curvy body, and he often sends me pictures of other girls, commenting on how cute or hot they are. He seems to find every lean girl attractive, which is starting to make me dislike my body. I’m about to turn 21, and I really need some advice on what to do in this situation.
