Hi, I'm new here and so I hope I'm posting in the right place.
Oh and I should mention that this is a guy she has known forever.
I think you saw your wife in a new light--that she could also be desired by another man, and it was normal for you to feel amorous towards her after that experience.I think it's inappropriate to ask someone who is taken to slow dance with you so closely and intimately. I think that fast dancing with friends is appropriate, as long as it's not all night and as long as you're not ignoring your significant other.
If it were me, I would tell my significant other that I'd prefer that slow dancing
I like blueorchid's response. I agree that your reaction is pretty normal in every respect, and that it's okay to tell her that it made you uncomfortable seeing her in an intimate position with another man. My guess is that she wouldn't enjoy seeing you like that with another woman (especially one you have admitted feelings for in the past).
She never admitted having feelings for him before.
Welcome to the board, Mwilldude ~
You're making perfect sense.
I guess that in a way that sounds like it makes sense.
If you try this, you will really be asking for trouble because she might enjoy the flirting too much and it might ruin your relationship.
