How to not be bitter or angry?

I want a baby but my husband doesn't. I've been trying to talk to him about it for a year. My patience is getting thin and everytime I look at him and I just feel this hot anger inside my stomach. I'm 25. We're stable. He just isn't ready but I am. I'm tired of it. I dont want to leave. I love him but I'm ready for him to be ready. Like wtf.
