Confused 🙄

So I dated my Bestfriend brother about 2 years ago but had to break it off because he cheated and wanted nothing to do with him my Bestfriend befriended the girl he cheated on me with we had a talk about that it was uncomfortable for me at first but I got over it because it's my Bestfriend he's still with the girl and I've had a relationship after and relations but he just recently had a baby and idk I guess I feel Wierd my Bestfriend was asking did I wanna see the baby and stuff and it was just so uncomfortable and I was kinda like ask me am I okay or something should she ask me that should I care ?
