where to start

So this awesome bull and I have been friends now for about a year. Shes like my best friend. We litterally don't go more than an hour or 2 every day without talking. I've always been attracted to her but know shes off limits because, well shes married. She also knows Ilike her too. Lately shes been acting a bit different and yesterday at lunch I noticed she took her wedding ring off . I love her to pieces and all the signs are there that its mutual. How can I approach her without risking our friendship, which means most to me. I feel that if she knew I knew it would embarrass her.you bulls are good at hinting but never directly telling. I just don't want her life ruined because of this but, I also cant just stop being her friend

She knows because, I told her a long time ago.

Now I know because we had a long talk this past weekend.

At least we both agree nothing can become of it. I just hope it won't hurt our friendship. Time will tell I guess.
