Missing My Friend... What do you think?

So I’ve had a best friend since 2008. She was my VERY bestfriend.. we did everything together. Around 2013 we had a “wild” night... she gave me oral.. THAT WAS IT!! After that I got in to a relationship with my (now) fiancé and I felt comfortable enough to tell him about my crazy times... After that, he didn’t want me to be friends with her. The situation we had, would NEVER happen again, and I miss my old bestfriends friendship. I’ve had a daughter since then and I so badly want her to be apart of my life again. She’s asked me to meet up to meet my daughter and catch up. Am I wrong for wanting the friendship back ?
