Projection and Monster are specific. What makes them specific is they are nearly always directed toward the spouse. They are usually behaviors that are not part of the MLCer pre-bomb drop. Anger and stress are normal things, Monster and Projection are not.
That's some interesting stuff, DGU... yes, I would certainly say that monster and projection do not occur pre-BD... yes, the usual "loud" complaint and the "you didn't do this or that" stuff... but not, by any means the anger and venom of monster and the "everything is your fault" suggestions...
As far as the in-fatuation stuff, true enough... although I'd guess that does sort of go both ways with MLC... the MLCer may not have an OP... but... it's also possible it's not for not trying... just for what appears to be the fact that they don't seem to think anything's wrong with that... because for all intents and purposes, they do not feel M... (as my W would say)... the WAS might have a love interest... but it's quite likely or more often than not, an OP is not a reason to leave... that there's not necessarily a STRONG EA and probably not an ongoing PA... of course IDK, but certainly stands to reason, I would think...
I'd say that a WAS knows they are M and feels they are M, they just no longer want to be... and as such, the rational of a (presumed) moral and sane individual would be that an A is not really an option...
Except in the cases of... can a person say "traditional" infidelity...? Where there could be a one time PA or a budding but as they say "unexpected" EA which the unfaithful spouse realizes was inappropriate... and generally work to stop it, or at least express some regret and remorse if caught... a WAS would probably do the same... whereas someone in MLC... well... they don't think they did anything wrong AND it's all the LBS fault, anyhow...
