Is Divorcing Over Infertility Justified?

On X, I saw a screenshot of what appeared to be a Reddit post from a wife whose husband is divorcing her over infertility.

The X account was appalled at what the man was doing.

If you say that marriage is for procreation, indeed multiplying (and you mean by that creating three or more children), then isn’t their marriage invalid? Isn’t he right to end it and seek another bride?

Adoption isn’t multiplying. Someone else has already had the child. Adoption can be a beautiful thing, but it’s not multiplying.

Multiplying is conceiving more children, and according to a popular pastor I’ve heard, it’s having three or more children, presumably those children living long enough to repeat the cycle.

If you’re a philosophical naturalist or have any other overarching beliefs about reality that indicate the “point” of life is to perpetuate your genes, then of course he should do what it takes to spread his genes. Most Western women aren’t going to support or even tolerate him doing that with another woman while still married to her. Would this man’s wife support using “third party” reproduction so ensure his genes continue?

Worldview matters here. If the point of life/marrying is multiplying or perpetuating genes, he’s justified in seeking someone else.

If someone is going to say he’s obligated to stay married to this woman and NOT spread his genes through other women or “third party” reproduction, then they are admitting that multiplying is not mandatory and not a highest priority. They should also explain under what conditions divorce is permitted and hold women to those standards, not only men.

If the point of marrying is simply companionship, why involve the government?

Whatever your position on these matters, consistency will make your claims more serious to your audience.
