Is NOBODY wrong in the post ? POST : Throw away account, mobile user, yada yada yada.

A bit of a background, My Ex and I, we dated for about 6 months last year. I was 17, and she was 16. I was pretty much her first love, and to me, I’m still not sure how I felt. It may have been love but let’s call it lust for now. Me and her still keep in contact regularly since she is a horned up individual and natural, (since I am a male) so am I. 

Recently one of my friends that I see and hangout with on a daily basis has started talking to her. I see him on her Snapchat stories and all that jazz. She asked me if I would be uncomfortable with them hanging out together. He most likely wants to have sex with her. He knows me and her have a history together but it doesn’t seem to bother him. I’m really not sure if I still have feelings for this girl but just hearing that has recently started making me wake up with night terrors about them dating. I’m starting to wonder if I should just let them do their thing, but that would probably end our friendship.

TLDR: Friend wants to hangout with ex and I really don’t want them to.
