So I started dating this girl about 5 months ago, when I met her she had told me about her past relations which I did not judge her about. One of the guys she had relations with was her best friend from her home town whom she said she was in love with but he broke her heart. I've always told her that she is and adult and she can do what shes wants, I would never tell her what to do. Shes been keeping a friendship with him through texting ever since we started dating. She told me yesterday that on Friday  they are going to hang out (she didn't tell me what they were going to do). Am I the asshole for not wanting her to hang out with this guy, ever. Really love this girl but I dont want to be hurt because of this. He is single, and about 2 months ago his girlfriend broke up with him.
