Well, another thought that comes to me is that this Four may also signify the guy's energy in the situation...that he may have felt you or the relationship were closing in on him too much, so he called it quits because of that. And, then as a mirror to that energy, it may pertain to you in that he now becomes "the one that got away," and that, in turn, results in the feeling that your psyche/heart still wants what it can't have.
Sometimes, though, it just takes a long time to get over people who have touched you deeply. And that is something you can't rush.
I never bend, fold, or mutilate. Unless I'm in a hurry.
