Thinking of our future, while he isn't.

So me and my boyfriend been together for a year and two months and we are always together every single day, so it's basically like we've been together forever. We love each other a lot and breaking up is not a option for none of us because we wouldnt like that. Every time I talk about the future we seem to disagree on sooo many things. I say abortion is wrong if the couple/people know the risk of sex and he says if I was pregnant we had to abort it, which I understand because we're just 18 but I'm not sure if he says that about our age or because that's what he wants to do if I have a kid. He also says he doesn't find being married that important If we both know we love each other which shocked me because who wouldn't want to be married with the love of their life ?? He also says he can't picture himself as a father and that he wouldn't mind no having Any kids, when he knows I want to have kids in the future really badly. I just don't know what to do everything he says comes out in a rude tone too as if he's telling me to not think about the future. What should I do? I don't want us to be 30 and I'm not married or I have no kids just because of him, being married and starting a family means a lot to me. I don't know whether he's just saying all this stuff because we're young and he's scared or if this he really what he means, I don't want to invest so much time just so I can be disappointed later..
