I think this "Straight" guy likes me?

His name is Garrett and well a lot of my friends thinks he's gay, he is cute and funny though. Well, he has been flirting with me a lot and grabbing my butt... but the thing that really makes me think that he is, is that the other day in Algebra II he said to me, "Your so cute when you try to be smart." Then today I made a fool of myself doing something and he was like "I love you anyway." What do you think? I hope he likes me P.S. I'm in the closet trying to find the key..
