You Bore His Child. Why Regret the Divorce?

"Repaying a debt? You call this repaying a debt?"
Lin Tianjin suddenly stood up, knocking over the chair beside him.
Bang!
The chair crashed heavily onto the floor, the dull sound echoing sharply through the otherwise silent room.
He stared fiercely at Su Kexin, his eyes blazing as if flames were about to burst forth. His fingers had turned slightly pale from restrained fury, trembling uncontrollably.
"Su Kexin, have you lost your mind?" he roared.
"For the sake of that so-called 'gratitude,' you're willing to bear Zhao Ziyu's child? What on earth is in your head? Mush? Or filth?"
"Husband... please don't be angry. Listen to me-"
Su Kexin rushed to explain, but-
"Su Kexin, what do you take me for?" Lin Tianjin cut her off, his voice hoarse with rage.
"Am I just a useless ornament in your life? A disposable chess piece you can sacrifice whenever you please?"
Every word seemed to be forced out from between clenched teeth, thick with disbelief and heart-wrenching pain.
Su Kexin suddenly sprang to her feet as well. She was like a lioness driven into a corner-her usual gentle, water-like demeanor shattered, replaced by stubborn defiance and grim resolve, as if she had become an entirely different person.
Her eyes were terrifyingly red, as though she had just cried herself to the point of collapse. They were bloodshot like a rabbit's, crisscrossed with dense veins, carrying a reckless, almost maddening determination.
"Husband, you don't understand anything!"
"Do you think I wanted this?" she cried.
"If it hadn't been for Zhao Ziyu back then, what kind of ending do you think I would've faced?"
"I might have been ruined by those lowlife thugs...
I might have been-"
Her voice broke.
"And now, he's kneeling before me, begging in pain, asking me to help him. How could I possibly harden my heart and refuse?"
