Associating with disfellowshipped ones can be a major hurdle for someone. Congrats on that.
Someone on this board once told me this (or something very very similar but I'm sure it was more clear when they said it):
If someone goes against their perceived authority figures for external reasons that person will likely bounce back to the rules that once confined them.
However, if that same individual goes against their perceived authority figures because they disagree with something then the authority figures have lost a little power and the all-encompassing authority they held is diminished.
Sounds like your wife is willingly thinking and making her own decisions without any coercion from you. Great.
