After another of Brooke Logan's betrayals, Ridge Forrester pulled a real Liam move and grew closer to his ex, Taylor Hayes. Hope Logan wanted her mother to be happy and for her marriage to remain intact, but Steffy Forrester pulled out all the stops to ensure her parents were reunited and their picture-perfect family was put back together. Steffy began hosting family events that only her father was invited to, isolating Brooke from his wife, and forcing her mother and father closer together (via Soap Dirt).
Hope was dealing with her own issues, meanwhile, with Thomas Forrester, but still, she didn't hesitate to stick up for her mother's marriage, fighting to keep Brooke and Ridge together. Eventually, a phony CPS call perpetrated by Thomas allowed for Ridge to leave Brooke, propose to Taylor, and stand at the altar to pledge his life to her once again. However, in a twist of fate that might have ended the feud between Steffy and Hope for good, Steffy spoke out against her brother, revealing his wrongdoings and vindicating Brooke in the process (via Soaps.com).
Brooke and Taylor both rejected Ridge, finally ending the cycle of his back and forth after thirty years of the same dance. With any luck, Hope and Steffy can avoid that kind of pain and exhaustion by ending their feud now instead of spending another two decades fighting over the same man or finding other reasons to maintain hostility.
