Best friend came on to me while drunk
I was out with friend over the weekend, and she was very drunk, i had to practically carry her home. She stayed at mine as she always does after a night out as it's closer. She was very chatty drunk, and out of nowhere tells me she's bi, and fancied me forever. Shortly after that she fell asleep, but i was so shocked. In the morning i wasn't sure she would remember, and didn't want it to be awkward, but she said nothing.
I don't know what to do. We have been friends since we were 6, and she has never shown any interest in girls.
I would call myself straight but when I was 13 or 14 i had a girl crush on my friend. I'm over it now, but maybe she felt the same at the time and still does.
Please any advice?
