Even though our "thing" didn't work out..you were a wonderful gift God sent to my life. You made me realize so much about myself and saved me from a shitty relationship I had been in. Now if only I had the courage to tell you how much I appreciated you.
Let's not forget, though, that words have power. Yes, they should be actionable as well, but that itself is part of the power of words, that "mere" words can create expectations, can forge bonds, can let someone down or lift them up. Say it, then show it.
