When a man can get pregnant and give birth to a child, then and only then does he have the right to any part of the decision.
Until then, respect the womans decision and shut the F*ck up.
Always remember the woman is the one who will spend the next 18 years raising the child, the man maybe if he sticks around or if he doesn’t, he may actually pay his child support, however I wouldn’t recommend having 3 childern at once to find out.
