its not a sick mind, the guy is just afraid on the unknown. Women tend to be emotional and competitive. They usually tend to demand what their friends/ neighbor has. If the neighbor goes n a foreign trip, she will ask for it too. someone she knows buys a car, she will dream for it too. Its human nature.
If you get a woman who is grounded to reality, its a gods gift.
BTW- controversial statement - you say there are 1000's of women worry about how their parents will manager her marriage, yes, that mostly poor people. educated woman have their threshold very clear. Thats why you find a lot of single woman in their 30's still waiting for their "prince charming". they would rather hit the wall than marry some one "beneath their status". They will mask this nonsense by saying " we need to find the right person".
