I don’t know where I stand..

Okay so me and my best friend have this different bond. We have slept with each other once & done bits when we are drunk few time’s.. we kiss all the time when drunk, we cuddle when we’re sober etc. But she is seeing a boy? I genuinely think I have grown feelings for her.. and I think the same has happened to her.. she would act jealous if I said other girls were talking to me.

I just don’t know what to do.. i can see she likes this fella so I’m just going take a step back.
