You mentioned romancing her etc....but have you talked to her, about how this is really making you "feel", about your emotions etc?
There are a great many women out there who don't really understand that men crave passion, just as many women do. Unfortunately a lot of women are raised that sex is something you do to take care of your H (which is what it sounds like your W does), but unfortunately many of us are also raised to erroneously believe that men crave the physical release primarily....and not the emotional side of things.
So...if you have talked to her what did your convo go like....if you haven't, why haven't you?
Oh...and stay away from those flirtatious situations, they are a slippery slope. I know the attention feels good, but if you are wanting to build your M with your W, stay away from those situations.
