Welcome to BPD Family, a peer support group of people who have "been there, experienced that". We're not here with legal advice, that is provided by lawyers, solicitors and other professionals. But our peer support includes
collective wisdom based on many years of hard-won experience.
Please browse our various boards, each one focused on a variety of things we have to deal with. For example, our
Tools and Skills workshops board has a variety of topics that are necessary to know but not very intuitive. Examples are identifying practical boundaries and using communication skills such as SET, DEARMAN, etc (and why logical JADE so often fails).
You mentioned your marriage is approaching a decade. If you're in the USA, one positive - in the midst of a world of hurt - is that both spouses of a 10+ year marriage can benefit from the higher of either spouse's income history once they reach retirement age.
You haven't mentioned whether you have children together, so I'll add this just in case... There are many reasons to ponder whether to divorce. One that is not so intuitive is how the children would be impacted. A common perception is that the marriage must be held together at all costs for the sake of the children. Yet the opposite might be true... If a person decides the marriage has failed due to serious mental health and behavioral dysfunction, the children
are impacted...
Living in a calm and stable home, even if only for part of their lives, will give the children a better example of normalcy for their own future relationships. Staying together would mean that's the only example of home life they would have known — discord, conflict, invalidation, alienation attempts, overall craziness, etc. Some 40 years ago the book Solomon's Children - Exploding the Myths of Divorce had an interesting observation (the earliest quote I could find) on page 195 by one participant, As the saying goes, "I'd rather come from a broken home than live in one." Ponder that. Taking action will enable your lives, or at least a part of your lives going forward, to be spent be in a calm, stable environment — your home, wherever that is — away from the blaming, emotional distortions, pressuring demands and manipulations, unpredictable ever-looming rages and outright chaos. And some of the flying monkeys too.
