For the sake of convenience, reliability and cost; the pill is for all intensive purposes the de-facto form of birth control used. The condom may be used, and in that case (the ONLY form of BC available to men) the man has responsibility.

If a man wants to avoid getting his wife pregnant, then he uses a condom- thus he cannot be tricked into pregnancy. If a woman does not want to become pregnant, she uses the pill, she doesn't just expect her partner to wear a condom. Either way, both parties better realize that pregnancy is a natural consequence of sex, and they learn to live with that risk.

You are missing the point. The point is lies and deception. If she uses a pin on his condoms, then she would be pregnant through lies and deception. The same thing if she says she is on the pill, and knows that she is flushing them down the toilet. If she claims to use the sponge, but never inserted it, there are dozens of forms of BC available to women, but just ONE available to men. (2 if you include abstainance, but that is grounds for divorce in and of itself).

If a wife insists that she is on the pill, yet the husband refuses not to wear a condom; he has by his actions, called his wife a liar. He may avoid the unwanted pregnancy, but he has played a card in a game he cannot win, quit or break even.
Face it, in a marriage, the wife determines when sex is permitted, how it will be done, and under what conditions. The male may suggest, he may make the first move; but ultimately it is the female's decision. If it were otherwise, then the husband would be tried for rape.
