I always enjoy reading poetry centered around the theme of love-lost and the disapointment that lingers long after. I think you conveyed your emotions well.
The word "bitter" just before dusk, could be changed to some other descriptive/verb more fitting. A word that conveys a masking of the sunset or a consuming of it maybe. Or take out dust and replace it with another noun: I know the dragging haze of love
What is Uz?

well.. dust does several things at once. First, it evokes the traditional christian funeral rites. The death of love as a corporeal entity, and the death of the body and soul as a result of lost love. Then it also alludes to the desert -- which works somewhat well with the car speeding off leaving behind a contrail. Creating, i hope, a more powerful image of abandonment. Dust also offers up that general idea of body dissipating - as most dust in a house is made up of human skin.
The bitterness offers 2 things that i want to hold, first is the image of breathing in the dead love. That taste of love gone bad. That taste of separation. Also, it reinforces the idea of desert and works off the stereotypes.
I will ponder them more though. Thanks Sin.

Great mixing of religious metaphor and love lost. In many ways, they are certainly akin. Your descriptors work well within both contexts and help to render a strong image, to this reader at least.
"the smooth of apathy under fingertips" - this line however, reads poorly. I feel there must be a word missing here, "the smooth pull of apathy under fingertips" perhaps? or better yet, "the smooth tide of apathy under fingertips", lending a greater allusion to the parchment of the desert elsewhere.
