Let's see, I started dating this guy June of my sophomore year...and I dont think he said it till April of my junior year, so about 10 months in. We were sleeping at my friends house on the floor and he just kinda whispered it then turned his back to me. I was like "HELLO! You can't just say that and turn around!!!" Haha...
Hate him now, but that was a cute moment for us.
