One of the most important decisions you can make in your life is who you get married to. If you get married to the wrong person, and you will know if you do, you need to make sure you don't have kids with that person. Otherwise, they will be tethered to you for life, and you can never totally leave them behind. The mom in this story has a useless husband who doesn't care enough about his baby to take care of him for a couple of hours, and I feel so bad for her. She is clearly an amazing mom who deserves so much better.
