<human>: I met her on an online MMO a few years back and I was smitten. We started dating long distance (she was in MD, I am in CA) after a few months of talking and after a year, she came over for a job and to move in with me. Things have been peachy and we've had a few minor arguments, but we both are good about talking things out. I'm thinking of marriage and with that comes with thinking about children.

I already knew she was childfree and she stated it at the beginning, but I was thinking she'd change her mind eventually and I was also in love with her and it didn't matter at the time. My siblings and coworkers are having kids and I would really like to raise one with her. We have a townhouse and we both make a good amount of money together to raise and support one. Anytime I bring up children, she gets dismissive or has a look of disdain. She has an IUD and she plans on getting essure (permament sterilization) once it expires in 2 years. 

I'm not sure what to do. On one hand, I love her and I want to marry her and be there for her until death, but on the other, I also really want children and she's not open to adoption or surrogacy because she dislikes them. I don't like to bring it up with her because she will tell me that I knew she was childfree before we even dated. I don't want to leave her, but it's been a dream to have one of my own.

Can you summarize the given text in a few sentences?
<bot>: I want kids, she's childfree. I want to marry her, but I have always dreamed of having one of my own.
