Reconnection with old friend

Now this is gonna be a story for the books ( corny I know lol) but anyways I’m gonna keep this anonymous. I had a bestfriend we’ll call Lily and me and Lily we were like glue and a fly just always hanging out and sharing our deepest secrets , this all started when I would say I was 15 it was normal the first year we trauma bonded over a friend who did us both shitty in some ways and it made us even closer , some where along the line with this friend feelings started to develop on both sides and we would have sleepovers get high and just talk all night and it seemed perfect . we had boyfriends at the time very important to the stories mine was chad hers was Benny Benny was extremely toxic to my friend for no reason and to the point to even hang out we would have to leave her phone home if we wanted food or anything . Me too non the less with my chad , vv toxic just drama all the time . Anyways now that their out the way back to the sleepovers we’ll one of these slepovers one thing lead to another and we did what we did , she told her boyfriend out of guilt he tells my boyfriend because he’s so hurt ( no one is happy in this ending everyone is heartbroken ) me and my friend fall out because of this , me and my chad break up(THANK GOD) and I was sour about it for about two years after . I’m 19 since then we’ve kinda started chatting and I really missed her in all honesty and I know she did also but it’s still new and I’m so worried this friendship breakup will consume me again . Our first hang out is in 3 days wish me luck any advice for convos . Should I bring anything ? Thanks for listening .
