Im just curious what is the difference between A mistress and wife???

the difference is that the wife has all the legal rights.maybe his wife become a nagger as time pass by.

Well they are both getting used. One is legally committed for life and the other he can dump at any time. A lot of guys get a mistress when they have reached a point in their life when they feel like they have it all, therefore they can do it all. Whatever he can't get the wife to do for him, he pays the mistress to do. Some women are turned on by men who are legally unavailable. They don't have to worry about the pressure of commitment and the man always has to show her the best of him, because she is always free to leave, but the wife is stuck.

I think men like the mistress more than their wife because the mistress is something new and different. the mistress will more likely do whatever the man wants her to do so he won't leave her because nine times out of ten she's a lonely person. I know sometimes I get tired of being with the same person, but I would never cheat. some people just can't fight their urges.
