Why Would You Opt-In to Single Parenthood?

It's one thing if you're young and mess around and get pregnant. But why would Winter declare she's going to get pregnant and have a baby by next year regardless of if she's in a relationship or not? Especially when she was raised by a single mother and knows how hard it is even if you have money? As a straight man I never understood why some women have this mindset since they'll be left with the lionshare of the child raising responsibilities. And if laws changed and men were given primary custody for out of wedlock children, I can guarantee that condom use would skyrocket lol
