annoyed

So me and my husband have been together for 4 years we have a 3 year old together and I have a 5 year old from a previous relationship. For the past year we have been talking about trying for another baby. He now says that he doesn't want to try for a baby and that we should focus on the boys and maybe in a few years we can. I had a miscarriage 1 1/2 years ago and we have had so rough patches. now I am at the point I don't know if we will ever get on the same page.
