So, Timelords have two Soulmates. Two hearts, two soulmates. It makes perfect sense! But when one of the Timelord's soulmate is lost or rejects the proposal of marriage, one of his hearts stops and his soul is ripped in half. Of course the Timelord can live with one heart, but it is very painful. Have you ever had your heart broken? Its about a thousand times worse than that...
