<human>: Can you condense the text into a few key points?

I am definitely not ready to have children and I don't particularly want children later in life. It's not something that I am even thinking about right now. If I fell pregnant at this time in my life I would get an abortion (I had a pregnancy scare a couple of months ago and when I said I would get an abortion if I had to, my boyfriend called me a murderer). The idea of childbirth actually kind of frightens and disgusts me and if I did want kids later on I like to think that I would adopt. 

My boyfriend talks about babies a lot and wants to be a father. He brings it up often even though he knows how I feel about the matter. The other day, we were talking about it again and he said, "Well, if you don't want to have my kids then this relationship is a waste of time, I'll have to go and find someone who will."

This really hurt me. To know that he would only be dating me to soften me up to bear his children, that he would leave me for someone who would have his kids if it came to it. And the fact that he said it as such a throwaway comment, it really hurt. 

I don't know if I should break up with him over this. Of course, I don't want to break up with him at all and I don't know how serious he was about this statement. When I told him how his statement made me feel he just kind of laughed it off like I was overreacting. Am I overreacting? I don't know what to do!
<bot>: My boyfriend wants kids in the future but I don't, he said that if I don't want to then our relationship is a waste of time. Should I leave him or am I overreacting?
