What's your take on boyfriends family being friends with his ex?

So my boyfriend's family still keeps in contact with his ex that he dated for two years. I only know this because Every time they comment on her Facebook or she comments on theirs. it shows up on my news feed. For example his grandpa told her she is so talented and he would still love to meet her one day. And told her she is welcome to visit. (he's wierdly obsessed with her) . His grandpa refused to come to dinner when my boyfriend decided for me to meet the rest of his family. My boyfriend and his ex just decided to break up because they weren't a good match and they fought a lot. Nothing bad. We just moved closer to His family. That has no idea I know they are close with her and no idea it bugs me so much. My boyfriend dosnt talk to her much. He tells me everything time she texts him about somthing. Which isn't often. I know I should let it go but it seems like they are all really close with her. And it just bugs me and I can't seem to shake it off. I have kept this feeling to myself. My boyfriend dosnt even know I feel this way about it.
