Say I Love You After Divorce

Seeing me with some other man, my husband mistakenly thought I was cheating on him. But that was actually my father! My husband proposed a divorce and I, knowing nothing, signed the divorce papers and left for abroad. Three years later, I returned to the country as a journalist, only to find him targeting and insulting me at every turn. His repeated hurt has finally made me give up on him entirely. At this time, he finally discovered the truth, and deeply regretted what he had done to me. Should I forgive him?
