As you said, she has done her homework and has been thinking about this for quite some time. Your best and only option is to get out of her way. To her, you equate to every negative emotion she’s been experiencing. She thinks that by getting away from you, she will be happy again. Let her have at it.
Here’s the thing though, I think there’s a lot of underlying factors for your W that have nothing to do with you. She has some demons, 44. You didn’t break her, and you can’t fix her.
Your best bet is to detach as much as possible and protect yourself legally. Clearly she’s consulted with a lawyer, I would suggest you start interviewing lawyers as well. I would not put it past your W to try and trick you into giving up some of your legal rights. She might even dangle reconciliation in your face to get you to agree to some things that would benefit her.
