My bestfriend likes me?

So my bestfriend (F, 21) told my husband (M,22) that she likes me more than a friend and that she wants our relationship to be more intimate. (Me and husband are open). She told him not to tell me, but he did anyways. So some back story I've known her since middle school and freshman yr of highschool I told her that I liked her more than a friend she told me she didn't feel the same and I was like okay cool end of story. Welllll now she likes me 6 years later, she thinks I don't like her like that anymore but I do. And I don't know how to tell her without her knowing my husband told me... so any advice?
