Desperate, Grandma turned to her daughters, "Are you heartless? This is our family's future! Agree now, or are you trying to kill me with worry?"

I thought about how Grandma had squeezed everything she could out of her daughters.

Now, with her son gone, she still expected them to prop up her daughter-in-law. Ridiculous.

Grandma's gaze then landed on me, filled with more accusation, "You and your haircut! It's your fault! Jack was too decent to just go out and drink and drive!"

Realizing this was going nowhere and bracing for more fallout, Susan and Mom shared a look and finally said, "Mom, go back home. Let us think this through."

With that, Grandma and Linda left.

Once they were gone, Susan revealed a staggering secret to my mom.

Jack had been infertile all along!

After much prodding, Susan finally spilled the beans, "During a routine work physical, it came out that Jack had fertility issues—his sperm count was too low to get anyone pregnant."

I was stunned and blurted out, "So Aunt Linda must've cheated on him."

Our top priority was finding proof of her affair.

"Look at this!"

Mom gasped, showing us her phone.
