"她比我小那么多，以后我老了她有精力可以伺候我", this sounds familiar to me,

 

I believe somebody I know said things like that to me too = he is planning to marry a young girl.  Back in my university days, a guy in my class dated a pretty girl but then dumped her after and dated a lot of other girls but finally settled down with a much younger woman. Men are very selfish.However, how much do you really think the woman loves him? anyway, 各取所需 ...

I agree with you: 在国内蹲久了，对国内女性的生存现状很是同情。所以也不怪这些女孩子。社会生存压力...
