Idk about the ‘vast majority’. All it takes is love, understanding and communication. You don’t even need a phone or wifi. Idk. I think if we cut the ones we love some slack and talk to them, idk how they hate us. Unless they are dyed in the wool Marxists i suppose. We have choice too, remember.
It also matters if the child is very young (which is better) and if the child's father is around (worse....who wants to deal with that?).
Women who think having a child with another man is not hugely damaging to them in the dating market are kidding themselves.
