Don't say anything. He knows you are commited. One of the biggest validations is allowing him to feel the way he feels. If you tell him you are committed, that is a sure fire way that he will see you as clingy, and you will push him further away. It is hard, because we think that by telling them that, they will realize how badly we want this. But trust me, it doesn't work.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
