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.
