She has used his mother as a reason to be separated from her husband, and he has nearly bent himself over backwards to prove his loyalty to her, but now, Wyatt (Darin Brooks) will begin warning Steffy (Jacqueline MacInnes Wood) that she is the one to blame for their marriage falling apart on The Bold and the Beautiful.

Wyatt realized the lengths Steffy would go to keep Quinn (Rena Sofer) away from Eric (John McCook), when he found out she and Ridge (Thorsten Kaye) tried to steal the Power of Attorney from her, and he was appalled when Steffy defended the action and ordered him not to tell Quinn the truth, something he refused to listen to, Now, in true Steffy fashion, while Wyatt tells Quinn the truth, she will turn to Liam (Scott Clifton) for comfort and validation about how she feels, com planning to him that Wyatt's actions will further destroy her life by giving Quinn more power than she deserves.

"She has control over my father, the company, my grandfather, and once again, she has control over my marriage," she says in a preview clip for the Tuesday, October 11 episode.

Later, after Wyatt has revealed the truth and returned home, Steffy will then confront him for doing what he did, and will try to claim that doing this will make things worse for them than they ever have been before-and will even blame Quinn for everything that has gone wrong in her life and their marriage-but Wyatt will silence her when he blames her for the problems they've had, defending his mother instead.

"How could you do this? You know how I feel about your mom! She's ruined my life, our marriage," Steffy cries in the clip.

"Because the success or failure of our marriage has nothing to do with my mother!" Wyatt fights back.
