Hate is such a strong word, maybe you don't hate kids, but just feel better when they're not around. It doesn't seem like you have discussed this with your husband, you should start there. You're young and have a lifetime to hate. Talk with a psychologist, sounds like you are depressed. If you don't want to have children, then don't. The fact that your husband wants another child is a good indication he doesn't know how you are feeling. Take your time.
