My big bro told me that his wife’s bff tried to seduce him, and he nearly gave in. He said she visited their home while his wife was at her shop. I repeatedly asked if he slept with her, and he insisted he didn’t, but admitted he briefly lost control, letting her press his face between her breasts while he grabbed her ass before fleeing. He’s now asking how to confess to his wife. 2 years ago, his wife privately told me he’s a recovering sex addict, a detail I never shared with him. I know he is recovering, but as a woman, I’m upset he nearly succumbed and touched her. As his sister, I’m torn on how to help him tell his wife.
