Gap Analysis?!

when the distance seems to increase with time
my days turn into nights, then to a blank space
nothing is wrong, yet everything is not fine either
grating, like a pulled thread in a border of lace

as the fire within still burns, lighting up the line
my fingers remember the curves of your face
cheeks tinged deep with the flush of rhum

this feeling's not for everyone,
can you define what it means to feel this way without a trace
this enigma of being and yet not being mine
i'm running hard but not keeping up the pace
what i want is not always what i can get
the gap is a void that's not always offset
