Don’t give him a back rub. Not until you’re much farther along.
Don’t tell him you’re into him. He should be the first to be explicit about how much he digs you.
Don’t plan everything around him. Life should go on even when you’re not with him.
Don’t use gushy emoticons in your notes. Smiley faces are fine. No hearts.
Don’t sleep with him or sleep over. Definitely a no-no until you know he’s smitten.
