Does he like me? Do I like him back?

I swim with him. He picks me up and twirls me around. He just gets me. He walks slowly with me. He always hugs me before I go. If I leave without one he puts on a puppy dog face and says, "What? No hug?" When I'm mad at him, he won't leave me alone. If I pretend he's not there, he gives me a hug around my stomach (I'm not facing him) and whispers in my ear. When I'm racing him, he always cheers for me. He does everything in his possible power to annoy me and he was trying to make me trip 2 days ago. He promised he would catch me if I actually fell. He helps me out of the pool when I'm hurt or too tired to get out alone. He's always there for me. I listen to his messages on my phone over and over again. He says I'm beautiful and says I smell good. I get high off of how he smells. He's all I ever think about now. I would do anything for him, and I know he would do the same for me. He's really protective.
