Middle-aged punk song (I remain)

I've finally
slept all night
and sort of
feeling right

i thought
i'd feel sad
but you're gone
and i'm feeling nothing but glad

i'd decided
that it might
be better
to give up the fight

but then you
and me split
and well at first
i'll admit that it sucked a bit

but now your split
and i'm perplexed
got time to think
when i'm not wrecked

told myself
i'm better off
without the hassle
and all of the strife

##

you left
i stayed
in this house that
me built

you split
i remained
but i'm convinced
and i'm not ashamed

you said
you'll move on
unconcerned
by the befuddlement
you left behind
