Fiancé Cheating With Step Sister Gets Kicked Out by Dad

The Original Post

After reading all your comments, I finally spoke to my father this morning. He was shocked when I told him everything.

I also confronted my step-sister face-to-face. At first, neither of them wanted to believe me they said I was lying. But when my father asked my fiancé to clarify over the phone, he finally admitted the truth.

After hearing this, my father kicked him out of the house and told my step-sister: *“If you want to marry him, go ahead but end your relationship with me.*

My stepmother tried to convince my father that my step-sister is immature and that I should forgive her, but my father stood firm.

By the way, I am now feeling very relaxed. I can’t believe I escaped such a difficult situation. Thank God.

I’m still processing everything, but I finally feel like I’m free from this mess and can focus on myself.
