Should I sleep with her or not?

Ok so about two weeks back I asked a question about was I selfish for being in love with my best friend who is married. I am too...long story and if you didn't read the last question I suppose you will be lost. She is married with three kids, I am married with children too, but for 14 years I have been in love with her. When we were about 16 or so, we did kiss, but it was to impress a guy she liked...for her anyways. For me it was bliss and I was completely loving every moment of it. So about twenty minutes ago I was on the phone with her (btw I have never confessed my feeling to her in fear that I will ruin to many people's lives) and I was explaining to her how miserable I was in my marriage (that is the truth) and that I am thinking about divorcing and switching teams and just being with women for the rest of my life (sorry if that statement offends anyone...I really am in love with a woman) So she says verbatim, well can you please tell me when you decide to do that so that I can sleep with you!!! I know the silence had to be crazy long because I lost my breath literally. She was like...Hello???? I said, yeah sure, I will let you know. She said, I'm serious (my name) because I would love to be with you. I said why, your married and have a GREAT relationship with your husband. How crazy would that be, plus that is an affair. Then is the crazy part. She said well, I have ALWAYS been curious what it would be like to be with a woman, remember when we made out that time for that guy I liked. She said I was so turned on I didn't know what to do, but I blew it off because I thought you would freak. I've always been curious what it would be like to sleep with you and your the only girl I trust. Sometimes when me and my husband are being nasty in bed, I tell him that I am dreaming about eating your P@@@@....I know this is graphic and mind you the whole time I couldn't breathe...this is seriously like everything I have prayed for in my life coming true before my eyes. I giggled like a high school girl ( blah) and said how funny (great response right) I said well what would (her husbands name) think about us doing that...you know experimenting. She said well he is fine with it. I said, your crazy girl and then pretended that I had an important phone call come in so I could come down here to my office and get on yahoo and ask you all WTF should I do?? Please don't judge me or think I am an awful person. Since I was 14 I have loved her...I mean with all my heart and I was so scared to tell her because I didn't know what that would mean for my life. Then she got married and then so did I and all of this was because I gave up. I was too much of a punk to open up and tell her. I came to terms with the fact that I would have to love her without letting her know and just suffer for the rest of my life. Now this happens and she tells me that she was turned on back then and she thinks about doing ual things to me when she is with her husband. Which is all I can think about when I have had with my spouse (also please don't judge there either, I have already filed legal separation papers so we aren't together really anymore) My question is, should I act on this or should I just let it go. I want serious answers please, no silly judge mental stuff. Please let me know what I should do. Just to clarify, if I were to go a long with this, it wouldn't be in a setting. It would be just with me and her. She just called me again and asked me if she freaked me out. I told her no but that I wanted to know why she is feeling this way. She said because she has always been attracted to me, but now she feels stupid because she thinks that maybe she went to far with her desires...I was like NO...don't feel stupid (OMG she must be crazy) I told her that I have been insane crazy about her too...she was silent and said, can I plan a trip to come up and see you (we live in different states) I told her to give me a bit to think things through...HELLLLLP....this is getting crazy. I want her so badly that I literally ache for her. Has anyone ever felt that way about anyone? The thing is, she is not the type to just got out and experiment because she is curious you know what I mean? So what does this mean for me? I never have wanted something so badly in my life
