Attention VS. Reality

Hi there ladies!
So I have been seeing a guy and we've known each other in high school since my junior year, his senior year. It's been four years since me and him have been in high school. I went off to college and he stayed back home and went to college. 
During the timeframe he has dated a girl for three months and broke up and I have dated my fair share as well but all of a sudden now he says that he's been interested in me since my junior year of high school and says that he loves me and wants to spend the rest of this life with me.
Does this sound sketchy or does he sound real? His intuition sounds fateful but when I'm not around him or his family he seems distant... 
 Advice?  I really like him but I don't want to end up being played.
