Well, this is upsetting.

Shortly after Real Housewives of New York star Ramona Singer confessed that she contemplated suicide in the wake of her husband, Mario’s affair, her 20-year-old daughter Avery penned a devastating letter to her cheating father and it’s sure to pull at your heartstrings.

Radar Online obtained the letter, which appears in her 58-year-old mother’s upcoming memoir, Life On The Ramona Coaster.

In the letter — written shortly after she learned of the 62-year-old’s infidelity — she says:

“I’m writing to you again because I hope that, as your daughter, I will be able to get through to you. You need to stop and fix your actions before you lose everything that is good in your life.

“We were trifecta and you broke us. What you have done and are still continuing to do is now forever damaging. You have no one to blame but yourself. It’s about time you stop acting like a teenage boy and take responsibility for your actions.

“This whole thing is an embarrassment to Mommy and me, and you have not once thought about how it would affect us. I am ashamed of you.”

After learning that her father brought his mistress, Kasey Dexter, to their vacation home, Avery was understandably distraught.

She writes, “How dare you bring her to our house that I grew up in in Southampton! We have endless memories in that home. That is the bed where you and your wife have slept for eighteen years. No sane husband would ever bring his mistress into his family home.”

In her memoir, Ramona writes that Avery’s letter inspired Mario to attempt to save their ill-fated marriage — but it was too late.

Even though she’s been through emotional trauma and experienced unthinkable heartache, Avery remains optimistic.

“I hope that one day soon, I’ll have the dad I always thought I knew and put on a pedestal my whole life,” she laments.
