Rules in the relationship are different subject.. We are talking about before you get into relationship! Woman needs to "invest" into relationship as much as man does.. Otherwise that relationship cant last!
If woman gets everything for free, would she appreciate and will man appreciate here more?

And rich is no subject too.. for some rich is if he has 1000 euros and for some rich is a billion.. And money should NOT be the subject at all if we are both getting to know eachother.. Why would i spend money on your trip? You want to know me, come.. I want to know you, i come to you.. simple as that..
