Actress Denise Richards has had it with her ex-husband, actor Charlie Sheen, reports.

Long after their volatile split, she claims he won’t stop texting her abusive messages.

“Last week, I sent Charlie a text message asking him if he’s going to Family Day (for daughter Sam’s school) and letting him know Sam was sick with a cold,” Richards allegedly told the New York Post. “His response was, ‘I hope you and your worthless retarded father get cancer and join your stupid mom. Rot in hell … ‘ My mom died of cancer. This is what I deal with on a weekly basis. He missed Dad’s Day at the school and my father had to go in his place. And this is how he talks to me?”

Richards is firing back after Sheen released comments to the Post’s Page Six column, calling her “beyond desperate.”

Sheen and Richards also recently clashed over an e-mail she allegedly sent begging for a sperm donation from Sheen.

Richards denied sending the e-mail.

“I have two beautiful kids. We’ll leave it at that. I am so over him. He’s the one who can’t move on. He’s disgusting and he’s hit an all-time low,” she reportedly added.
