I really need advice? Air Force?

My boyfriend of 3 years, that I've lived with for a year and we are currently 9 weeks pregnant, has been talking about joining the Air Force, with that he will be deployed all over for years and yes I will get to go as well if we are married as long as it is safe. My problem is I don't want to move away from my family for that long, especially with having a baby or toddler, I want our kids to have a good relationship with there grandparents and aunts/uncles, cousins and have a steady home base with friends they can have all growing up. We have 3 dogs, and it's gonna way to hard to pack them and everything we have every 2 years and fly half a world a way. It's not something I ever wanted to do. He makes it seem like it's the only good job he could ever get and they only thing that will make him happy. I want him to be happy but I won't and I already know it. I don't know what to do. He is so pushy about it and I can't see my self being okay with it. I'm just not the right person for it. Some people are, I'm just not. So I need help what do I do, I'm stuck in the middle of giving up my happiness or making him give his up. Don't get me wrong it has nothing to do with joining the military, I think that's wonderful that he wants to serve our country, it's the moving away that I can't handle.
