I used to want kids - now I don't

I've been married to my husband for a little over three years. I always assumed I would want kids, but as I've grown older - and my family has continued to spawn litters of kids - I've realized I'm just not that interested. My husband and I had to take care of our niece for two days because her mom died of a heart attack. She was only 30! I realized that I don't want to have kids, I want to have a life. I want to be able to travel where and when I want and be able to do that for the rest of my life. I want to have the freedom to do whatever I want to without having to think about how it will impact my kids, because I didn't have any. I want to go back to school and get a degree I actually like, instead of one I got because I can do it from home and take care of children. I want to sleep in and have a quiet house. And yet, I can't help but feel guilty for feeling this way. Like I'm somehow doing a disservice to the people around me. But really, I'm doing a disservice to myself by not doing what I want to. <br><br>Am I wrong for not wanting kids? Should I wish for my life to be complicated and difficult and noisy?<br><br>TLDR - I used to want to have kids, now I don't. That makes me feel guilty.
