Am I doing too much ?

Ok so i have been with my boyfriend for 4 months now but since the beginning he's done this. So first off he's into music and photo shoots and he has a rnb group with his brothers right, so the first thing I noticed was that his followers are 90% female I'm probably exaggerating but whatever I'm angry. Anyways he likes so much pictures of these girls I don't mind the head shots or the cool places and stuff it's the ones where they are naked and showing off their ass and tits that get me fucken angry I caught him once and he said he wouldn't do it but then I accidentally saw in his feed that he was still doing it. I don't know why but it just makes my blood boil when I see him give these hoes attention idk what to do help me
