Hi! I found a similar question asked elsewhere, so the answer there might help you:

Your best friend is your best friend and will always be someone special to you no matter what. . .

Why do anything that can change that bond? The way you ask your question, comes across as quite selfish, do you care about her feelings more than self-gratification? The word 'use' is not so nice, perhaps you meant to say something like you just wish to try to see? You should just have an honest conversation. .

You're not so sure of yourself either. . .

Resolve your doubts as much as you can and then talk to her. . . . If you don't want to hurt her feelings, then don't hurt them.
