Recently I became paranoid that my boyfriend, who is really good friends with one of my best friends, would start to want to be with her instead of me. I told them both that I felt threatened and my boyfriend understood and reassured me that they were only friends and could never be anything more because of the way they interacted. I trust them both and I believe them. Anyway, a few days after I spoke to them about how I felt and got it resolved, my friend brought it up again and started to act really moody with me. She said that she felt like I didn't trust her anymore but I do! I wasn't sure why because she doesn't really have much to do with the matter apart from being the girl that I felt threatened by. She told me to think about others involved and how they felt so I asked her how she felt and she said it wasn't about her and blew me off. Why is she bringing it all up again after we solved the problem? How can I prove that I trust them and how can I fix our friendship? Please help!!
