who's foible?

What kind of addiction is this?
Addicted to another human being!
like a parasite
one sided
still justified!
The addict is restless
till he is satiated
and chattel
is helpless
not because
it is bound
but because
it is justified!

The addict suffers
if not contented
and the chattel
if he is!
who's foible is it?
somebody else's
not theirs!!
