Hi Atari25,
Sadly gaslighting and storytelling is one of those things that will hit you hard. You will be the bad guy in her stories, and best you can do is to acknowledge it is nothing more than her current twisted take on history. You have no need to forget or change your own memories, instead cherish them and share them with your loved ones.
Also take good care of yourself. Mentally and physically and spiritually The next 6-10 months will be hardest ones of your life, so prioritize your well-being. Anxiety is common (until you truly learn to separate what you control and what you do not), so are anger, frustration, despair and even love. The more you can keep your eyeballs on you and your own emotional wellbeing, the less you will hurt. And don't worry if you fail, everyone here has failed time and again... slow down whenever you can. There is no rush anywhere (it's just the discomfort of anxiety that's making it feel like you need to act asap).
It is also good to acknowledge this is not about you. You cannot push her out of this. And you cannot nice her out. She is going through a personal crisis, and it will end only when she hits the bottom and wants out of it (and sadly it can take years and years, possibly forever). Sadly her crisis has created another crisis for you and your family. It is something you can control.Focus on resolving it.
How to navigate through .... It seems keeping future talks on strictly business (kids, logistics etc) from this point onwards is best route for many. She is not telling you everything, and you need to learn the same. Avoid personal relationship talks with her. For yourself find a good therapist, also feel free to vent here. For myself journaling was and is a lifesafer in organizing my chaotic thoughts.
Last but not least, be there for your children. Even if they are on early stages of adulthood, they will need support and love of a sane parent possibly more than ever.
Hugs and strength,
Alvin
