So there's this guy.. Let's call him Ryan. And Ryan and I have a 'thing' meaning we just hug and flirt a lot. Yes, we both like each other. But today was the last day of school. And there's a stairwell thing at my school. No one was there except me and him. He stopped me and hugged me. Then he said "Don't talk." and started to get closer to me. But, I started moving away from him to walk down the stairs. After that, "Ryan'' sent me a text message saying "I've wanted to kiss you for so long." The only bad part about this is that he has a girlfriend. I made that clear (through text) that I will not do ANYTHING with him, unless he is single. And he said "Just one kiss. Please?" and I said that I wouldn't do that when he has a girlfriend. We did not kiss. We haven't done anything past a hug. Sorry about how long that was. What should I do?
