The thing that has the most effect on a man’s experience of fatherhood is the woman he chooses as the receptacle of his seed. If he chooses a woman whom he knows will carry even an unplanned pregnancy to term, and one whom he knows will agree to share parental rights, then he will experience fatherhood. It would be even better if he has already married this woman.
Unfortunately some men will choose to have sex with a woman whose views on abortion they have not bothered to learn. Nor will they have bothered to learn whether their sex partner will fight sharing custody with the biological fathers.
Then these men will whine when these sex partners, whom they barely know, choose to have abortions, or choose to fight these men for custody.
As a woman, I can only ask, what did you expect? What did you plan for?
As a man, I can only ask. Do women ever lie?. How do you know if a woman is putting on an act? A lot of good men have been destroyed by lies. A lot of women and men only show their true selves after marriage.
