You sound pretty intelligent to me, and more people should think this way. I wouldn’t feel anything except smart for making a decision based on my personal feelings regarding the time, money, and energy I’d be using to raise kids. People have kids all the time because someone else wants them to have them. Then they kids come, and there is no time to work on your relationship. Every waking moment, brain cell, and every penny you earn goes to ensuring this little being you decided to create has what it needs (and more of what it wants) to become a decent little person.
And let’s not even get into genetics. What if you kids is born unhealthy? What if your relationship fails because of neglect? What happens if you lose your job and can no longer afford a family? More people should think like you. I wish I would’ve.
