<human>: Like I said I do not want children. I find them repulsive. I would be perfectly happy living a childless life. My fiance loves children and wants to become a father eventually. I have told my him many times that I do not want children, but he doesn't seem to believe me. He tells me that my mind will change when the time is right. I have explained to him that it isn't that I'm not ready, it's that I don't want them at all. I enjoy my freedom and don't want to dedicate 18+ years of my life caring for another human. I love him very much, but I hate the thought of marrying him and denying him something he wants so badly. What do I do?

Can you condense the text into three sentences or less?
