If there’s a breakup, 50-50 is best. (Both) keep that in mind throughout the marriage.
Who wants to get married if they’ll see 50% of their children? The ease with which people retreat to divorcing instead of resolving issues should give any man pause; we are still years away from divorce being as detrimental to women as it is to men.
For anyone that thinks I paint with a broad brush, why do you think 1) men are hesitant to marry/breed, and 2) women aren’t so hesitant to initiate a divorce? Even if we assume responsibility for failed marriages are split evenly, the results are certainly skewed against men. The millions of men that are quite content to go on to the next life without ever marrying or breeding can’t all be wrong; they’ve seen the effects on prior generations and are politely declining...
In the interests of full disclosure, I’ve been married for more than 20 years and have children; I just never presume that this life is for everyone, and made sure I married a woman from a culture that still frowns on divorce as an undesirable outcome.
