Difference between love and friendship??

Crystal • I need friends... 😂😂

So I’m 13, and recently my best friend ever told me she likes me as more than a friend, but wasn’t completely sure about her sexuality or her feelings. I didn’t quite know how to respond. Yeah, I’ve thought about her that way and she is very beautiful, but where does the line of friendship end and feelings begin? I don’t know if I just admire her or like that way. Pleeeease help!
