It may be the end of an era.
"I don't believe that co-hosting together is a viable option anymore," a source tells PEOPLE. "Anything is possible, but that doesn't seem like a viable option. Practically, it's a different dynamic now."
That could spell disaster for the show.
Ripa, 45, didn't come to work Wednesday after a source said she felt "hurt and beyond betrayed" by the way management told her Strahan, 44, was leaving. She had planned to take Thursday, Friday and Monday off to celebrate her 20th anniversary with Mark Consuelos, but, says a source, canceled her trip to Turks & Caicos at the last minute.
"Michael has called her and reached out to her and texted her, and she is not acknowledging him," a second source told PEOPLE, adding that Ripa had gone "radio silent" when it came to dealing with management – or letting them know if she planned to return to work on Tuesday – and that staffers were becoming nervous.
"Nobody knows if she will return to work Tuesday or not, and the people are very nervous. They're flying blind," says the second source. "The longer she stays silent the more concerned they get."
But the first source says Ripa's choice to remain silent has been entirely deliberate.
"She wanted to take a step back right now," says the source. "She's not saying anything because she wants to take the time to think about it. There's stuff the network has to demonstrate to her as well insofar as their commitment to the show. She and Michael always had a decent relationship. Her issue here is with the management's actions."
Now, says the source, she has to consider what her next move will be.
"She has to decide whether she can sit there with Michael again. It doesn't seem like that's going to be something possible. But she's trying to make a smart decision not a rash decision."
