Regarding changing states of residence, before forcing a move first find out from lawyers in each state (in
confidential legal consultations) what the typical outcome is for support issues in divorces after a long marriage. While there are still some states that issue lifetime alimony, more states are switching to "transition & training" alimony for a few years to give the disadvantaged spouse time and opportunity to adjust to post-marriage life and find a career or get training for one.
However, if your spouse has a chronic health problem that may be a situation where a court could grant longer alimony.
She verbally abuses. She never backs down on any feeling or opinion. She can't be convinced her opinion is not more important than anyone else's.
Hmm, sounds like my ex, and so many other ex-spouses.
Meanwhile, if she has been verbally abusing you, it would be a good idea to quietly document (=record) them because if you later report her verbal abuse and she naturally denies it or claims you're the actual abuser, you would need some support for your claims. That means don't shove a phone recorder or whatever in her face, quietly means "as though you were doing nothing out of the ordinary". You don't want to needless trigger your spouse.
