Partners search history

I seen in my boyfriend Instagram search recents that he had looked at his ex’s boyfriend’s profile

And on his Instagram he has 2 photos of my partners ex in just undies

One she’s leaving over and you have a full view of her butt crack and Vagina.

The other she’s just standing and the photos from behind

I don’t know why he would search for him. He doesn’t know him

I don’t know how to feel
