Bfs feed and overthinking issues

I have the worst overthinking problems ever. My bf feed is like girl asses doing the big bank trend from tik tok. And he say and doesn’t go on Instagram but he said he might be from the past because he watched that shit in our relationship in the past. But like this trend isn’t that old. Idk. We’ve been together for a year and 7 months. He’s messed up with that type of stuff many times I’m the beginning and kinda middle of our relationship. We’re really good now and I do trust him but idk just it’s fucked em up in the head and it’s a shame. I feel bad for my past self for dealing with that shit and the effects I have from it today. I just need opinions or whatever please. We’ve been so so good and what changed for me it’s just his feed and ugh idk.
