I was in love with my BFF

I was so in love with my BFF like we kinda flirted all the time and I was littlerly the reason she realized she was bisexual?! But I never told her cause she had a Boyfriend the entire time (who she was way too good for) but I was just hoping they would split and I could finnaly tell her and maybe we could get together?? But I never did and now it is too late because we are no longer close plus she is pregnant with his kid now!
