My mother-in-law expected me to clean her house. My husband threatened divorce when I refused. He wasn’t prepared for my response.

That afternoon, I overheard her talking to Ethan.

“When you finally start making money again, don’t put all of it into this household. Keep some separate. You can never be too careful with women.”

That evening, I reviewed the authorized-user credit card Ethan was supposed to use for groceries.

There were charges from sports bars.

Video game purchases.

Gas stations.

A florist.

On March 8, there was a charge for an $180 bouquet.

He had given me three tulips from the grocery store.

I didn’t confront him.

I changed my banking passwords, lowered the limit on his card, and stopped paying for anything that wasn’t necessary.

When the card was declined at a gas station, he called me furious.

“You embarrassed me in front of everyone.”

“Then pay for gas yourself.”

“You’re obsessed with money.”

“No. I’m the one earning it.”

After that, everything became worse.

Margaret started calling constantly.

Her back hurt.

Her water heater made strange noises.

Her kitchen faucet dripped.

One evening, she asked me to drive across town and mop her bathroom because a plumber had supposedly left “a disaster.”

I said no.

Two weeks later, I returned from work a little before nine and found Margaret stretched across my sofa.

Her feet were wrapped in a blanket and resting on my marble coffee table.

“My mom’s blood pressure went up,” Ethan announced. “She’s staying here for a few days. She’ll sleep in our bedroom.”

“Her condo is twenty minutes away.”

Margaret sighed heavily.

“If I’m such a burden, I suppose I can just go home and die alone.”

“Rachel, make her some tea,” Ethan ordered. “And wipe down the hallway. Mom spilled her herbal drops.”

“Do it yourself.”

He looked at me as though I had insulted him.

“What did you say?”

“I said I’m not your maid. And I’m not your mother’s maid either.”

That was when he said the sentence that finished breaking something that had already been cracking for months.
