I think I hear "I love you" way more often than I think, it's when he gets up in the middle of the night and brings me back a drink.
It's, "do not wake her up, yet" and "honey, go back to bed"
It's how he sits in front of me and wipes away every tear I shed.
It's how he kisses me so sweetly every morning before he leaves and returns to do the same thing every single eve. 
He cuddles up to me so neither one of us will get cold and then he starts of sentences with "so when we are old..."
I think I hear "I love you" more often than I know
It's in the little things, like him watching all my shows. 
It's when we go to eat and he picks my favorite place. 
And how he knows my mood just by looking at my face. 
I think I hear "I love you" in fact, I know I do.
I just hope he never has to wonder if I love him too.
