They had been together since they were very young, I would not be surprised if Barry was Suzanne’s one love in her life. They raised two children together, and I believe that Suzanne may have felt that marriage was for eternity. If circumstances, say an employment opportunity or a new fresh start might present themself, a dutiful, loving wife might agree to something that she had hesitation about. Plenty of people move for a spouse. I wonder if Suzanne ever lived in fear of him-did she ever believe he could kill? For some reason, I feel like she saw the good in him. Maybe not enough to stay married to him, or obey him when she had had enough. I do feel on some level this is all about money.
