maybe? the apple of your eye?
the exhaled breath, you held?
a gratuitous golden sigh?

I could be the paint that dried
that you so intently watched
or the grass that is greener
on the other side
except you never jumped the fence
I'm just a skirt you tossed

I wish I was a lone fish
in the bowl of busy life
except wishes are fishes to you
so industriously multiplying

How about,
*I'm your wife?
