If you want to let him know about your feeling, but you have difficulty getting the words out, try putting your emotions in a letter. After all, women aren’t the only ones who appreciate a good love letter, and you don’t have to wait for a special occasion express yourself. 
Feeling Romantic
My Sweet Rufus,
If you wonder just how much I love you, wonder no more. You are the sun in my sky, the river that runs through my soul, and the very air I breathe. Before I met you, I didn’t believe it was possible to love someone so deeply and completely, but you have given me faith that true love really does exist because I share it with you.
Totally yours,
Caroline
