"you want me to be jealous, don't you?", and she admitted that she did, that she considered it a sign of love.

Well, it is a sign of connection, whether it is unhealthy or not can be debated. A man who shows no jealousy at all seems strange to me. Too emotionally controlled, rigid, withdrawn. So I get what she is saying there.

Well, as I mentioned to LustForLife, my reaction tends to be along the lines of giving her more attention, flirting with her, and so on. LFL seemed to consider this inadequate; my W, on the other hand, appears to eat it right up, at least for now.

I said it was inadequate? Not sure when that was but it doesn't matter what works for me, only what works with your W.

The simple truth is that the thought of her having a fling with another guy turns me on, especially if I get to watch. Of course the thought of her cutting me off emotionally and sexually, or running off to live with him, doesn't turn me on at all, so I haven't exactly come out and admitted any of this or deliberately done anything that would tend to encourage her to cross the line.

Hmmm... I can see the fantasy part of it I guess but no way would that be a good idea in reality. Goes back to my first point about the need for some jealousy/possessiveness/connection.
It would eventually blow up in your face. She would resent you for it. Feel like you didn't really love her. (My opinion of course but I'm probably not too far off). Women do not want a man that wants to pass her around so that you can "get off." I can see the appeal in some aspects but only in a purely sexual R, NOT in a M. Just doesn't tend to work.
But you know that Crazy.
