- I know I love you because my heart feels as if it weighs a ton when I'm around you or even when I'm just thinking of you.
- I know I love you because I wish I could be by your side at all times because I love the feeling of overwhelming happiness I get when you merely look me in the eyes.
- I know I love you because you're always on my mind even if we spend the whole day together, I'm always thinking of you.
- I know I love you because when we talk, even if we run out of things to talk about, the silience doesn't bother, becuase I know you're there.
- I know I love you because I don't care what other people think when they (as in He) see(s) us together and totally ignores the both of us.
- I know I love you because I've never been happier in my life because I know someone is there for me and will pick me up if I fall.
I know it's short, but I hope it means as much to you as it does to me.
