Boy Problems! Please help!?

does your friend know that this boy is interested in only you? if she doesn then she may be upset..tell her and she will know that her chances are up. i know i sound blunt but if shes your best mate she will be happy for you and know that she cant have him.. all best friends have a crisis to do with boys. but if you got with this boy..would u be comfortable being with him and your best mate at the same time?
