Now here is my little anecdote:

Someone close to me moved with his girlfriend after about a year of them dating (he's around 25). They became engaged and were starting to plan a wedding for this summer, until things started to go south. Now he is bumming at my house a lot as his ex-fiance moves his things from the bedroom into the living room as he tries to avoid her. He managed to get out of his lease early (thank goodness for a nice landlord) and he'll be moving in with friends soon but how freaking awkward is that? These are the things you have to think about-- how it may end if it goes badly. And college is such a special time for you not to enjoy while you can. Like others have said, you have the rest of your lives to live together if that's what may happen for you two. And talk it over with him. See if he has any input on the matter. It is a two way street, after all.
