He's been very nice to me, he's nice to me in front of people, and when it's just the two of us. Sometimes, though, he's mean to a girl friend of mine. I understand why, she completely stalks me, but that's still no excuse. I don't know, he acts like he really likes me, but he... has a wall surrounding him. I don't know if that means that he is not ready, or that he's just leading me on. Any suggestions?
