long story short, im a female, bi. and I have this close friend, we've been friends since freshman year, now juniors. she has a bf

but lately we've developed this flirty/sexual relationship, like how we text eachother. she thinks im really cute, last time we saw eachother, after we left she texted me saying she wanted to kiss my cheek.

little things like this make me wonder if she likes me back or its just cus we're so close? any opinions?
