If you have a torrid summer fling with a hot co-ed but you broke up after Labor Day, 10 years later will you be able to put the ending out of your head and just remember the good times? Probably if it was an amicable breakup, like if the Tigers lost a pennant race that was close and hard fought the whole way. But this collapse is the equivalent of not only her breaking up with you, but doing so after cheating on you with some loser dude. Hard to erase and move past that.
