I did not say he was raping her. It is his responsibilty to care for and love his wife. Surely a doctor has told them that every pregnancy after about #7 is high risk for the woman. Even if she is willing to have more children, it is the husband’s responsibility to care for her and preserve her health to the best of his ability. This means not impregnating her every year.
What an antique idea of the responsibilities within a marriage. Has it occurred to you that if she is determined to have another child that she can arrange for it without his knowledge or assistance.
