He was floored when he learned that his daughter was planning to marry Bill after catching Liam and Hope together. Now, Ridge will make one last attempt to convince Steffy to rethink her plans for the future on the Monday, July 30 episode of "The Bold and the Beautiful."

After hearing about Hope (Annika Noelle) and Liam's (Scott Clifton) make out session after the fashion show on the CBS soap, Ridge (Thorsten Kaye) was already worked up, because he felt his daughter, Steffy (Jacqueline MacInnes Wood) had been betrayed. However, after going to Bill's (Don Diamont) house to warn him to stay away from his daughter once again, he was stunned when Wyatt (Darin Brooks) informed him that the two were engaged to be married.

Now, he has run to his daughter and will beg her to reconsider what she plans. However, Steffy will remain adamant that she's doing what's best for her and Kelly because she can't trust Liam to be around Hope.

"If Liam finds Hope so irresistible, then he can be with her," she says in a preview clip for the episode. "I'm done, I'm done. I'm going to move on with Bill."

"Think about this! You've got to stop this before you're in too deep!" Ridge shouts.

However, no matter how much he begs, Steffy will refuse to budge, and may even give him her reasons for doing what she's done. She previously told Liam (Scott Clifton) that she was going to be with Bill because it was clear he would never be able to really choose between her and Hope, and she wasn't going to let herself or their daughter suffer as a result. After watching Ridge do the same thing for years with her own mother, Taylor (Hunter Tylo) and Brooke (Katherine Kelly Lang), she has refused to repeat history.

Meanwhile, Wyatt will continue being disgusted by how his father is handling things, and how he's willing to throw any chance of repairing his relationship with Liam in the garbage, as Bill confirms he plans to marry Steffy as soon as possible.

"Liam sealed his own fate," he says in the clip. "And now, I'm going to seal mine."

"The Bold and the Beautiful" airs weekdays at 1:30 p.m. EDT on CBS.
