Adopted ... searching?

We adopted a daughter
And five years ago
She wanted help
Finding the ones
Whose seed did sow
Her genes and her
Personality, her
Outward appearance, too
So that is what
We helped her do
We found them, we did
And then it began
Her yearning for them
And her abandonment plan
She left her husband
And all of us then
We haven't seen her much
In those five years since when
But families are complicated
It has been hell, it's true
But hopefully she's happy
While we've been sad and blue
Time helps a little, no
Make that a lot
We knew her back then
Now, we do not
But she can never take away
The growing up girl we loved
For in our hearts
We signed her name in blood
