How to talk about future stuff with bf?

So…. I have a problem. I just dont know how to talk about the whole future stuff with my boyfriend. Ive tried, only to appear nervous and choke on my words every time. The best I could get out one time was “where ever you go, I want to go too”. Thing is though, he isnt ready to talk about this stuff yet. Im not asking him to move in with me now and marry me now and devote his life to me now. But, I want to feel like our future together is safe. I want to know that he does plan to live with me one day. Sure, this is going to have to happen after we graduate college, but thats in about 1 year for him and 2 for me. We both do plan to get our masters though.

But anyway, thing is, I just dont know how to talk to him about it. I choke up each time and I get nervous and embarrassed. How do I talk to him about such serious issues? What should I say, and ask? Or, should I stop even thinking of such things and just let us be the way it is now? Weve been together 2 years, which I figured was long enough…..
