Interesting view.

The only thing that makes us live with other people without finding any difficulty is that we have different thinking.

Not quite sure about this though. Mutual respect for differences in perspective would be one way to put this, however having different thinking alone might not be something that keeps two people together.
If we were to assume that to be true, all the matchmaking sites have been doing it wrong as they try to find similarities to calculate compatibility instead of finding differences to predict how two different individuals would get along.

The most reason of divorcing is that two people have one way of thinking.

Not quite sure on this one either. I am not yet married so I might not be qualified to talk much on this. However, if two people had one way of thinking, I'd assume that there'd be less of disagreement and more of agreement. In case of pride and prejudice, if both reacted the same way - waiting for the other one to apologize or in case of constant exchange of blames - this would indeed hold true.
