i think the best advice i can give u is to tell her exactly how u feel and take the outcome as is. if you feel u can still be her friend and putting the the fact that u love her aside then go for it. but if its too hard now that u know for sure that ur in love with her and u cant stand the fact of the person u love possibly talking to other people then i think the choice is urs to make. everything u do in life has a consequence but its ur choice to pick which outcome u'd perfer. u know?
