Fwiw I think one of the 'fault lines' in MLC is that some of them do know there is something the matter, and others absolutely refuse to see this. You see it with posters here - spouses who know they are conflicted, realising they might be making a big mistake. Then there are ones like my xh who has remained adamant that there is nothing the matter with them [and it is the rest of us that have got it dead wrong]
