This is one of those "to my ex" poems that I tend not to care about, but I don't want to let that ruin it for me. I like how you opened the poem, an unusual couple of words, nice imagery there.
As for the ending, why do you want to push away memory when it's all you have left? I think the good memories should be embraced, not cast aside just because they happen to reflect something that no longer can be. Eh, just my two cents...
Faith is a fine invention
When gentlemen can see
But microscopes are prudent
In an emergency.
