Yes really, must they talk?
Sometimes, I feel some remarks or questions are just a show of sarcasm. They are meant to rob in salt on an injury that's still hurting badly.
I usually would ignore such sarcastic remarks or questions.
As for the issue of infertility, it could even be the fault of the man. However, in Africa, once a marriage is unfruitful, people would always point accusing fingers at the woman. This is totally inappropriate. Infertility issues in marriage should be addressed with wisdom and understanding. Affected couples should seek medical and whatever help required. Getting divorced is not the solution. I have seen couples who endured and took the right steps together, and today they have children after so many years of marriage.
