He says hes coming back, should I wait?

It's called putting you on the Hook. If you watch my show you'll know what I mean. A good way of telling if someone's putting you on their hook is if they keep saying 'right now'. For example, "I don't want to be with you. Right now." He's stringing you along but not committing and leaving you around just in case, as a backup girlfriend. 'Right now' paints a picture of a magical future when everyone will work out between you but the truth is, it will never happen. True story.
