You want to know how you can tell if you're meant to be with someone? Just sit and have a conversation. Some people when you talk to them, it's like trying to listen to classical music on a radio with no antenna. You can push that dial back and forth all you want, but you only get the static. But when you're meant to be with someone, and they truly are the one, you just sit, start talking and a Beethoven sonata will begin to play.
