Ex is being confusing

My ex and I broke up in March 2023. We have been in no contact since then but I find his behaviour to be very confusing. So I know he has a new girlfriend (I think they started dating in the summer). He unfollowed me on Instagram 8 months after the breakup, however to this very day, I am still on his private story on Snapchat and we’re still friends on everything else (Spotify, Pinterest, Twitter, Facebook, VSCO??). Is this normal? I’m not really bothered by it but it did make me a little curious as to why he’s doing this… Let me know I guess 😭
