*sigh* Matchmaking is an arduous process and most CERTAINLY not for imperceptive amateurs (no offense Queenie) or else this is the most expected outcome.
If I were to get to know them and speak to each of them directly, like over MSN, I could help them out to at least tolerate each other and even at times show some affection, but in all honesty, they are bad,
bad,
BAD for each other. And their greatest stumbling blocks are their own lack of maturity. The extreme jealousy that each harbors with the other will continue to tear each other apart. It is best that they never enter a deep relationship. Have them break it off entirely. Their natures are too conflicting. This relationship is unsalvageable.
