No KP… you are not selfish or anything.. But I must say this is very nice of you to think about this in the begning.. i have seen couple of girls in my family to got married to guys who were from a bit middle class family and girls we from rich family.. first they thought they can live with.. But after marriage problems start growing like they liked to eat out everyday and the guys family wanted to go out for dinner only on weekeds and other problems.. so i think girl or guy should start think about this before marriage..
