Yes I think they have changed. Its unevitable and a sign of the times. As to what some others have said, I think you already realise some of the changes yourself subconciously from the way you behave.
But what I find puzzling is that you are probably one of those dudes belonging to the "upper class". Rich and educated. For such a successful person which I "presume" you are, why should you allow those shallow women to dicate your life and your feelings.
The more successful you are, the less you should trust women. "Hint,Hint"
The fact is I don't think you should even commit yourself to one person until you are sure of how she is like. Some ladies might regard this as a "low-down" method and a sign of insincerity. But it the playing field is fair and I dare say local ladies also do the same although in a more "subtle" and less obvious way.
Of course if you ultimately really want to find someone who can accept you for who you are, you can simply conceal your $ and your "paper". But you and I know how your chances will stand then
So its up to you. Really.
