Do men really have exclusive and unchanging feelings?

In my perception, people's feelings are changing rapidly, there will be no one to a person exclusively unchanging, especially men, interested in all the good.

There is a friend, in our view, mature and stable, capable of career-oriented family love wife, drink too much will tell all the friends brightly, I love my wife, she is the woman I want to live a generation I will never give up her. But the wife is suspicious and sensitive, one day found him chatting with a girl, caring sick caring to send medicine ...... I was in a trance, in the end she was sensitive he could not stand to find someone else, or he had looked for someone else before she was so sensitive.

The success of men is often not in how many women you can find at any time, but has been accompanied by your woman is how a state.
