Should i tell her how i feel or not risk our friendship?!?!?!?!?!?!?

I am going to be honest with you things don't always work out like you plan . I was in you situation two days ago I told her that I am in love with her since we have known each other for three years too and she is bi sexual and so am I . She sadly didn't feel the same way becsuse she likes another girl. If you know she doesn't like anyone else then go for it . Best of luck
