Charlie's angel spilt

Samantha
So 2 girls and I were like best friends we met at work and we just clicked, we hung out almost everyday! Partied, adventures, dinners, fitness etc. then one of the girls and I got in a big stupid fight in march and stopped talking. Now the other girl was stuck in the middle of me and the other girl trying to keep both of us as her friend. 
Flashback to now it's November the other girl I still talk to mentioned that I should talk to her again say "hey it was in the past, it was stupid, I'm over it, are we cool?" Which sounds like an awkward conversation waiting to happen. I get that the other girl wants her friends back but idk what to do about it. I feel like even if I did talk to her 1. It's been like 7months too late 2. The friendship won't be the same as before what's the point?
Maybe someone can give me some advice has this happened to anyone before?
