I was in your shoes 4 years ago... today I am happy to say my wife and kids have all abandoned that dumpster fire of a religion. Each situation is different but like you I left abruptly and my wife was blazing angry and sad all at the same time. I tried to tell her all the things I knew and it only made matters worse.
My best advice to you is just give it time. It is neither prudent nor fair to her to force her down the path. If she is of the type that can see through the bullshit, she will eventually make changes because she knows you will be there to support her.
I would also suggest that you still demonstrate that you love her and want to be with her and that your decision does not mean you want to break up the family. Many people I know who were married and left all said that that was one of their spouses biggest fears.
