Funny thing, 4 years after my divorce, I think I'm suffering from the same thing. My ex did such a good job of being a jerk to me those last couple of years, I find it difficult to remember any of the good times in the marriage! I KNOW there were plenty - we actually had a very happy marriage for most of those 24 years - but darned if I can remember anything right now except for the crappy times. It's like he contaminated all my good memories.
