A long time ago, like 7 years, I had the biggest crush on this boy, but nothing ever happened. I lost contact with him, and I never knew what happened to him until this year. We re-met through mutual friends. He and one of my friends were dating for a minute, but they never officially became boyfriend and girlfriend. She decided that she didn't like him anymore, and they are no longer dating. Now he wants to ask me out. What should I do?
