Quinn (Rena Sofer) was finally given the ultimatum she feared most over her relationship with Eric (John McCook), but despite not wanting her son to potentially lose his own marriage, she may make a decision to out herself first, which will have dire consequences for Wyatt (Darin Brooks) and Steffy (Jacqueline MacInnes Wood) on The Bold and the Beautiful.

In a last effort to separate Quinn from her grandfather, Steffy warned her that if she didn't end things with Eric and leave the mansion, then she would go home and end her marriage to Wyatt. However, Quinn may stand her ground and tell Steffy she can't force her to give up what she wants, and after Steffy leaves, Quinn will admit to Eric that she may have made things worse on her son by potentially giving Steffy the grounds to end their marriage.

"She said because I'm not moving out of here, she's going to move out on him," she says in a preview clip for the Monday, August 22 episode.

Meanwhile, Steffy will in fact return home to Wyatt and tell him that she went to try and convince Quinn to not only leave, and when he asks his wife how it went, she will inform him of what she said.

"I told Quinn if she didn't move out, I would," Steffy says.

Wyatt will be stunned that she made such an ultimatum, and after realizing his mother refused to move out of the Forrester Mansion, he will wonder if that means his wife is going to be true to her word. And when she possibly confirms that she will be because it won't send a message to Quinn unless she does it, he will be left to beg her not to give up on him or their relationship.

"I would do anything for you," he says in the clip. "Just don't leave Steffy."

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
