What should I say to a boy about slowing things down? please help!!?

Just wait for a few weeks. Don't rush into things. Sounds like this guy might be trying too hard, or just isn't using his head. Maybe wait for him to approach you again. If he does, then he's interested. If you don't hear back in a few weeks or so, it may just have been something at the moment. Maybe he doesn't have many friends that are girls and isn't too sure how to act. Maybe he just wants to be friends? I don't know. My advice, just wait it out. You just got out of a relationship and getting right back into one may only hurt you later. Just take some time. Enjoy the single life and have fun with your friends. Just don't rush into another relationship after breaking up with someone.
