Don’t know what to think

Hard situation..

So for the past while (months) me and my bestfriend when we are drinking we have kissed not a big deal..

She tells me she isn’t bi which is ok but it’s everytime we drink we kissed..

Now about a month ago we slept together & it wasn’t one big awkward 🤷🏻‍♀️ but she said it was a one off won’t happen again..

So we were drinking last night and it got hot and dirty she fingered me etc.. she tells me she isn’t bi but wants to keep doing this.. don’t even know why I’m writing this 🤷🏻‍♀️🤦🏻‍♀️
