I am a synonym for "timid"

Suddenly
I find it hard to breathe
even without you standing
next to me
only reliving the memory

and everything beautiful
you make me feel
cannot conceal
the pain, equally real

and your eyes,
no longer mine
captivated by the shine
of her, so fine

I can only resolve
myself to absolve
of this
wonderful misery

(excuse me,
while I find a way
to smile politely
as I remove my fragile heart
from your clumsy, unwitting hands
and make my final retreat
into isolation)
