I was talking to a friend earlier today who's in a very similar situation to myself. He's got an ex he's still not quite over, and a newer girl who he's involved with. He didn't understand why he still would think about his ex, even though he knew he never wanted to get back together with her. That's when I thought about the following idea:

When two people fall in love, it's like two pieces of metal getting molded together in perfect unison. Over the course of time, these two lovers melt into each other forging a bond that's stronger than either one individually. Even when the fire and the passion burns away, there is a strong foundation and an unbreakable mold left behind to fall back on. As the inevitable fallout ensures, the metal, this bond, slowly starts getting chipped away, piece by piece; and by the end, you're left with two pieces, their ends jagged and painful. What's worse is that the metal that melted together still contains pieces of the other person, and until all of those pieces have been removed, there will always be pain.
