Meh, doesn't really matter to me one way or the other. Hell when I was younger and sleeping on park benches and friends sofas I actively sought out women that made more then me...of course the girl working the McDonalds drive thru at the time would have met that criteria.
I don't know...in the grand scheme of getting to know somebody, falling in love and trying to build a life together it just seems like how much she makes is pretty low on the list (outside of the "can we afford the one or two bedroom apartment and such). If she held it over my head or something then I suppose it would become an issue...but the same could be true of anyone I guess. No, I'm just not really bothered by it one way or the other, if all the other key factors towards building a relationship are present its just too small an issue to worry about.
"honey, I love you, you're the girl of my dreams but that damn brain surgeon salary is just to much for my delicate male ego...I'm sorry its over."
The only real problem is see is weather or not the two people in a relationship can strike a balance. Am I dragging her down because I can't afford the lifestyle she leads? Will she mind that I can't come on that cruise I can't afford? Will she pay so I can? Is she okay with my bums salary? Now I've been on both sides of those issues and they can be bitch to work through but in my experience its more about two people being in very different places in life then about who makes the most money.
...meh I'm just rambling now, you folks get the idea.
