Precisely. People spend their whole lives looking for their other half or soulmate, then they find them at last and run in the other direction because they're not the glorified dream they thought it would be. They bring out things you don't want to talk about, feel or do & you'd rather forget. But you'll never feel about anyone else the way you feel about them, and if you settle in life with that person who was a bit easier for you to handle than 'the one' you'll never forget him/her. You'll realise that you never really loved till you loved them and you can't love another in that same way. 

And let me tell you, you will be. But my God, is it worth it.
