The conspiracy of the husband's family

My husband had his legs amputated due to a car accident, but his parents went on a trip at this time, leaving me alone to take care of him at home.

I have taken care of him diligently for seven years, pouring water into his bowl and working tirelessly from morning till night.

But when his life was on the brink of death, his parents came back and fabricated evidence of my infidelity.
