I think that in every relationship one person is into it more than the other. We are individuals after all, and that is OK!
Based on his actions, your situation seems far from unrequited love.
You being more outward about your feelings in no way means that his don't run deep. It takes me a long, long time to be "all in" with love - but the feelings are there far before I openly agree (for lack of a better word) to being in love - if that makes any sense. Sure, it's a defense mechanism...we all have them.
So far, is he worth it to you to wait for it?
