From what I have read, learned ... now that the A is 'out' ... its not longer the dirty secret, its real, a real relationship. Some of that drug has quickly worn off ... as your W starts coming out of that fog, things are going to become very very real for her, the fact she blew up a M, a family, all that ... the guilt will come in waves, some of this she will project onto you ... some she will swallow and try to deal with.
She will act differently ... maybe hate you more, maybe blame you, ask why you forced her into this mess, maybe nice you into things she wants ... regardless your dynamic has shifted considerably so I would suspect 'movement' by her.
This A will run its course, just the fact there is light on it now. Time will tell.
