All I know is that she was still contacting Jack up to 2 months ago. Jack says she doesn't look happy, but he doesn't love her anymore. He has a new GF, feels there is no stress and the relationship with his new GF is much more relaxed and "I don't have to look over my shoulder anymore".
I don't know what boundaries BH but down, maybe very little. Maybe he took her back with very little questions. 2 years away from his WW, he took her back.
