A guy who has been married before how would his attitude be to a girl he would be getting married to as compared to the one who has never been married before? would there be any difference?
Do you really believe that there is a well known equation ? Each "case" is on it's own merits (there are many parameters to consider most of them are personal parameters [e.g: his personality, is he a learning person - just 2 to mention]). There is no way to give you a clear definite answer.
I guess i knew this even before asking but i'm too worried to help myself.
