Nowadays, in the smartphone era, there's a fast and easy way out on everything and people are pickier than ever. shyt before that, since the introduction of fast food, so now everything gotta be fast food even relationships. In vitro fertilization is an easy answer to the problem that is relationships. Women and Men around the world have a problem with each other, especially American Men and Women, so this is an easy fix. They get what they want without having to deal with a man which is good for them.
What I don't understand is, after having your child, presumably with the intentions of not having to deal with a man, why put yourself back on the dating market looking for a man?
Women are much smarter than men, but attracting a man isn't that difficult, it's very simple, really.
