Given the amount of time you have already known him and the viewpoint you have established on him, I don't think there is a very good chance that your feelings about him will change. Anything is possible but the only way they would change is if you and your subconscious really wants to change, and from what your saying I don't think that's going to happen.

I definitely think relationships do grow overtime. The more you hang around the person, talk, and get to know them there is a pretty good possibility that you will get attached to the person and your bond will become a lot stronger and the feelings will get a little more intense.
