Don't know if this is similar, but my BIL was a gardener/ play area handyman and he was up on scaffolding fixing some swings and fell through it. He eventually lost his job due to other factors but a couple of years later, having suffered major depression he had a seizure, then it was established that he had MS which had lain dormant from birth.
My BIL has behaved in the exact same way as my h has. His wife is now in the process of leaving him and he was absolutely terrible to her steaming back to just after his accident. She too was blamed for everything over the course of some 7 years now and my BIL has never relented, yet stays in the same house. Prior to this she was his everything.
