I don't know what to do, help ?

Ok so I need some help... I'm biual and I am in love with my bestfriend and that is a fact, I know I love her, she is fully aware of this but she doesn't feel the same we are just really close friends, as I say I love her more than anyone or anything in this world, but the past couple of days I have been thinking that I think I have feelings for the girl she loves, I don't know what to do, should I tell her or wait ?
