Why won't he tell me how he feels about me?

We've been dating for year now. I've professed my love for him after about 8 months and I still do here and there. Even though he still will not reciprocate.

PS we have a great relationship, rarely fight and have everything in common. His family loves me and so do his friends and vis versa.
I guess I'm so used to having men profess right away that this is throwing me for a loop.
