When I suggested that you simply and directly express your feelings without imbuing the message with BIG HEAVY MEANING (beyond the wonderful content of your words), I didn't necessarily mean to say you should be nonchalant about it, exactly. I just meant not to overthink and worry about the moment you tell him or his response. Just say what you feel when you feel it and it will be allright.
The world opens up... when you do.
Oh, oh, can't you see? Love is the drug for me. ~Bryan Ferry
"Love is that condition in which another person's happiness is essential to your own." ~Robert Heinlein
