Moving In!!

My Boyfriend & I Havent Been Together Very Long But He Keeps Hinting ( More Like Insisting ) That I Should Move In w. Him AND His Roomate. The Thing Is That, We Are Neighbors... Like Literally Across The Hall From Eachother. I Just Dont Understand Why Its So Important To Him Right Now. I Guess Im Just Looking For Some Advice On How To Handle This Situation.
