In part to satisfy my personal curiousity and also in order that I may, hopefully, be of service to you in predicting how your H may react if he is required to vacate the marital home, which numbered questions in the quiz that you've provided a link to did you score as 0 and which numbers did you score as 1?
Obviously, studies of the socio/pscychopathic personality has moved on since 1997 but, FWIW, if you scored 2 for questions 1-6 (albeit I have reservations about the wording of question 4), 10, and 17, I have no hesitation, on the basis of what you have said about him, in stating that in all probability your H is a sociopath.
If a Court orders him to leave the marital home, will he be able to immediately move in with his df or db - albeit temporarily - or will he have to accomodate himself in a hotel/b&b until such time as he is able find a permanent place to lay his head?
Am I correct in assuming that he is unware of your consultations with solicitors etc? If this is the case, he will be taking the view that he can afford to play the long game and, effectively, wait you out in the expectation that financial and other considerations together with his blandishments will leave you with no alternative but to return to him.
I suspect that when he discovered your absence, he shat himself expected that the long arm of the law would shortly be on his doorstep and I'm prepared to believe that, that night at least, he stayed awake long into the early hours frantically endeavouring to spin a convincing explanation of what he said to you.
In order to come up with a believeable or acceptable explanation, he would have tried out various possibilities from 'it was a joke - my dw took it the wrong way' to outright denial that he said any such thing.
However, given that he was not confronted by the boys/girls in blue in respect of the conversation he initiated with you last Sunday, he will have undoubtedly rapidly reached the conclusion that he 'got with away it' hence the clothing and food that was delivered to you by his db, which was occasioned as much by his sense of relief that he wouldn't be brought to account as his desire to persuade others that he is a reasonable and honourable man.
In so generously sending these items to you, he has begun the process of setting himself up as the victim of your unreasonableness and it's likely that he's playing this role to the hilt to his family members and in his dealings with anyone who enquires about your sudden absence/whereabouts. It's also likely that he will be diffidently - almost humbly - implying that he's as much to blame as you while, of course, believing no such thing.
IMO, at the present time, no matter what he's telling you about how sorry he is, wants to change, get help etc, his mood is one of complacency.
It's unsurprising that many sociopaths are drawn to the worlds of politics and acting because these fields offer optimum opportunity for their condition to go undetected and undiagnosed.
