Antipathy

Shall I put the bank service charge on him?
She says, she does to teach him a lesson:
In his own fiscal misery he'll swim,
And a lesson is taught in rejection;
It wouldn't hurt to change my ties status,
And delete my workplace on social sites;
She says, leaving him in cirrosiratus,
He won't find her now but try as he might;
But he finds this and his feelings are hurt,
A sinking in his chest, ache in his heart;
Nor is his self-esteem his just deserts,
Sometimes, he wishes he wasn't so smart:
     So long as biology ruling man,
     So long lives heartache, throughout time began!
