His wife has told him she has every intention of walking out the door because his mother is still with her grandfather and is even taking the relationship to the next level, and now, all Wyatt (Darin Brooks) can do is beg Steffy (Jacqueline MacInnes Wood) not to go on The Bold and the Beautiful.

Steffy told him she had to leave not only because she had given Quinn (Rena Sofer) an ultimatum that if she didn't leave Eric (John McCook) that she would leave Wyatt (and Quinn chose to stay in her relationship), but because she feels he has failed to do the one thing she asked him to, which was keep his mother out of their lives. Now, he is begging Steffy not to do this, and telling her he isn't giving up on them as easily as she seems to want to.

"I won't let you walk out that door," he says in a preview clip for the Tuesday, August 23 episode.

However, Steffy has her doubts and reservations, and a part of her still feels as if she was tricked into the marriage because Quinn has kept Liam (Scott Clifton) out of the picture and seemingly disinterested long enough for her to move on, and she will remind Wyatt that being Quinn's daughter-in-law means she has to deal with her, and she can't have a happy life that has Quinn in it.

"I can't risk Quinn being in my life," she says.

Wyatt won't let that deter him however when it comes to convincing her to stay with him, as he will have one thing he can promise her, which is that despite his DNA, he can be more than Quinn's son, and can easily cut her off if it is what will make Steffy happy, since his number one goal is doing just that.

"I am not Quinn Fuller's son right now, I am you husband," he says in the clip. "I am 100 percent dedicated to you."
