Husbands sperm count

So my cousin is in her late 20s an is married to a man who has low sperm count(close to having none at all). They were try the first two years of their marriage to get pregnant an then found out their only chance is if he gets surgery. He told her he will never do it. 5years into their marriage an still no baby. He refuses to adopt. Refuses to have the surgery done. Says a baby is not worth all the hassle. So my question is could you stay with a man who couldn't/wouldn't give you a child?
