There are many factors that could influence his decision. First, look at what's going on in his life right now. Is he busy with work, is he short money? Talk to him about it. After 2 years, you should know that communication is key. Let him know how you feel and make sure you understand how he feels. Either come up with a compromise or realize that you are two different people wanting two different things and should move on. It could save you from a bad break-up and in the least, you should remain friends.

Best of luck. :)
