Olá João!
It sucks, for sure. My own marriage was on the rocks for a while as my wife struggled with the idea of me (and my son) distancing ourselves from "the truth" while she tried to hold on to her beliefs as much as she could.
She had mixed days. Sometimes she would seem to listen to our criticism of the Watchtower, then something would trigger her and she would go ballistic and in full defense mode.
Our marriage was on the rocks for a while, when I feared that she might well choose the religion over her marriage. People in high places in Bethel in Alcabideche told her in no uncertain terms that she should consider a biblical separation because I, as an apostate, under my laid back surface, was just a monster in disguise, kind of a ware wolf that may turn under the moonlight.
I decided that no amount of words and "proof" would get results; I just would be the best person I could be for her, and braced myself for a long, 'cold war' marriage, that someday might end up in a split of her initiative.
Fortunately, being patient and loving paid off because my wife saw the light by herself, and reached her own conclusions by connecting the dots after stumbling on Barbara Anderson's website. Maybe it was hearing it from a woman's voice, maybe it was the child sex abuse that ticked her ... in any case, she made the best decision one fine morning and just told it to a dumbfounded husband.
João, if you love your wife and I'm sure you do, just be patient and give her some room to breathe. In time her eyes will start seeing the cracks on the surface of the WT. Brace yourself for the 'winter', hoping that spring comes next.
