LOVE. HELP. Oh the depth of feeling.

This is a very awkward topic for me, but, ill just spill it, i love my boss. a purely platonic love, but very deep indeed, and i know he feels the same about me from the little things he says and how he cares for me. i know he will not mis- interpret or get weird if i tell him, but i just can't figure out how. He is my mentor, teacher, creative soul mate, treats me like a equal, highly values my intellect and intelligence, he and i finish each other's thoughts with out even having to speak. how would you tell him if you were in my situation?
