I want to piggyback off what Mr B said in his post above. You read who your W was in her journal many years ago. That’s the person she has always been and probably masked it for awhile. I believe you wrote you never had the passwords for her devices. That’s not normal. Not saying your W cheated but she’s probably been up to no good your entire marriage. I know is doesn’t feel like it now but be thankful she waited until your kids were older.
You don’t need her to coparent you don’t need her for anything. Eliminate her from your life completely. If and it’s a big if that she is ever willing to do the extremely hard work and face her demons and earn another chance with you then you can cross that bridge when you come to it.
