My sister engaged in an affair with my husband. I disowned them both, and we haven’t spoken for six years. Then she contacted me out of nowhere, shouting that I had cursed her—that he loved her but not me. She had five miscarriages, and after the last one, he abandoned her for another woman.

Then came the true shock: she had cancer, and treatment was costly. I made a big donation to help cover her medical expenses without her knowledge. I changed my phone number later, so she’d never know it was me.

Regardless of what she did, I cared. I just couldn’t tell her.
