“Sharon has clearly been emotional since the news broke but is maintaining that confidence everyone knows her for,” a source tells PEOPLE. “She’s dealing with a lot but she is not distraught.”
Sharon, 63, and Ozzy, 67, have been married 33 years.
“This is not the first time she’s been through this – she’s just not taking it quietly this time,” the source continues.
News of their split broke Saturday amid rumors of infidelity on Ozzy’s part. Sharon addressed infidelity rumors on Tuesday’s The Talk, telling her co-hosts: “I’m 63 years of age, and I can’t keep living like this.”
She also said that she’s “been avoiding looking at any pictures or reading anything.”
“I know what’s going on. I don’t need to read about or see about it,” Sharon said. “It’s like putting salt in a wound. I don’t need to.”
Sharon said she kicked Ozzy out of their house, but he has moved back in and she is staying elsewhere.
A source told PEOPLE earlier Tuesday that despite the split, divorce isn’t necessarily on the table.
Sharon and Ozzy have three children together – Aimee, 32; Kelly, 31; and Jack, 30.
