Why? Just why?

why are these female that don't care to have the responsibility to raise their child, due to wanting to party or just don't care to be a mother, but can end up pregnant in a blink of an eye, while some of us ladies are sitting on the sidelines begging and praying to have babies and we can't. Why? Amber ( ex step sister 😂) has had 4 precious babies and she has nothing to do with none of them. with in 3 weeks of giving birth to each one she would take them to a friend's house and never show back up, a year later she pregnant again. Why can't the roles be reversed the women who want babies can have then in a blink of an eye, and the irresponsible ones can sit on the side lines. I have been TTC with my second one for over 6 years, why can't it be easy for me?
