Advice needed

My husband and I have been together for over 7 years, married for almost two. We discussed having children years ago, before we were ever engaged and we both agreed we want at least one child. I've been asking to TTC for about a year now and he's now telling me he doesn't know if he wants children or not. He's saying he may have changed his mind. He says he doesn't want to lose his freedom. He likes being able to go out every weekend and have dinner, go to breweries, hang with friends, etc. I've explained to him that I want a baby and now. I've explained how important it is to me. He's not a good communicator and I don't know what to do. Help!
