My mother is mad that me and my fiance dont want kids. She's a bad mother and I don't want to repeat this behavior.

Hello, I'm 25 years old. My fiance is 28. Never wanted kids. I grew up with my brother, and I just don't like kids. Our wedding is next year. We planned to have kids in 5 years. <br><br>2 months ago, I found out that I have endometriosis. Really bad. I'm scheduled to have a procedure in a few weeks. I decided to adopt after doing more research and learning more about my condition. I realized that I'm kind of not good with kids. I'm not very patient.<br><br>My mother is a single parent. My parents divorced when I was 7. My dad cheated on her and left. She is really angry about this. I don't want kids now. I think I made the right decision. My brother is really mean, I don't spend time with him. I think what she is mad about is that I've decided I'm done with my family. I don't want any of them in my life, especially my brother.<br><br>I don't want this, I just know I'll be a bad mother. I like my free time, I don't want to be a mother. I feel like she is telling me I have to be a mother because I am a daughter. I love my dog and I understand why. I'm a parent to my dog and I can barely manage. My mom is really mean. I don't want to say more, I was raised by a woman who was extremely heartbroken and trying to punish me and my brother for being there. <br><br>My fiance doesn't want kids. She loves kids but doesn't want to be a mother. She is 100% behind me. I think adopting isn't the best idea. I'm just going to focus on my life. I won't have kids.
