Should I reach out to my ex-best friend?

So a SUPER long story short, about a year ago me and my best friend of almost 10 years stopped being friends. Obviously there have been times that I’ve really missed her, but what she did to me was really fucked up but yet blames me for everything that was wrong with our friendship. I know I’m not perfect and I made mistakes just like everyone else but I owned up to what I had done wrong (unlike her) Well anyways, today I was going through a box of old stuff and it really made me miss our friendship. A very large part of me never wants to be her friend again or even talk to her, but another small part wants to reminisce about all the good times we had. Idk what to do. Should I reach out to her and what would I even say??
