A little upset

So in December, my husband's and I briefly talked about having another baby. We have 2 which are 9 and 8. We're both 30 years old. I came ro a conclusion of actually trying for another baby. He even told some of his family he wanted another baby. So, once I thought about it and actually really want another baby, my husband now doesn't want one. I'm a little upset by it. I know I shouldn't be because its his decision too but I just want to experience it again. He gives valid reasons as to why, for example like taking the kids to Disney land, etc. Basically giving them our full attention, which I COMPLETELY understand but I also feel like I'm missing that little extra in my family. Has anybody else been through this?
