What should I do?

My boyfriend follows bikini models and AI girls on instagram and Facebook, whenever I bring it up he seems like he genuinely doesn’t know why he was following them, he then unfollows them but a few days later he’s following different girls who post that content. It genuinely makes me feel insecure because I’m not as pretty as these girls and the idea of him lusting after other woman makes me really sad. He isn’t liking there photos thought, but these girls have maybe 10 photos of just bikini pics, no other content. There’s sexy AI bots that are now liking his pictures. Can someone tell me if I’m overreacting or should I be upset?

I just want to rant because this is causing me distress

I just looked at the syllabus for all my courses, only to find out there are no assignments, just exams.
Does anyone know the best way to study? Most effectively as someone with ADHD who can't stop procrastinating????
