Does a man have the right to cheat if his trad wife doesn't keep up her end of the bargain?

In most relationships these days, both partners have jobs. But in some cultures, there's the concept of "trad wife" where the man is the sole bread winner and the wife stays at home.

In these relationships, her role is to keep a clean house, cook meals, look pretty, and be pregnant.

But if she just sits and watches daytime TV all day, doesn't do the housework, alonly serves ready meals, and lets herself go, does he have the right to cheat?
