Childfree by choice. I'll be the first to admit that I'm selfish: I want my husband to be all mine and remain my husband, not just my baby daddy. I want my space to be clean and free from noise. I want to watch any shows out there, scold vulgarities freely, and I want to sleep in. I want to travel or meet my (childfree) friends at a moment's notice.
Before you judge me, think about why you want children? Because you WANT (insert reasons here)... You don't need children. There are many reasons for wanting kids, and I respect everyone's reasons. I used to be in teaching, and raising a child is a tough job. Only when you judge me for my childfree existence then do I turn the judgment onto you.
No, I do not need "permission" from my husband to not have children. Are we living in the mid-20th century? I make sure the one I choose is someone whom I love to be around and can see myself growing old with, and whose beliefs are similar to mine.
I'm not sure how fertile I am, but I did plenty of research and made sure my contraceptive is reliable. This is MY choice. However, I have a few friends who are childless not by choice, but circumstances prevent them from becoming parents. They want to have children and would have made great parents.
These friends are the reasons why I think it's bloody rude for nosy people to ask why couples do not have children! Because these couples may be facing problems and suffering. They are not doing so to "save face". Save what "face"? They're simply trying to be strong and not break down.
