Yeah obviously your wife is abusive, she should not be constantly telling other people that you’re a bad person, especially for something as stupid as you’re not doing chores. And her trying to turn the kids against you is really sick.
If I were you I would be getting a divorce immediately, and I would be telling all of the kids and all of your friends and all of your family (everybody she’s ever badmouthed you to) that you’re divorcing your wife because your wife is abusive and constantly bad nothing you for no reason.
I would send a large, mass message to everyone, documenting what your marriage has been like and how she’s systematically told everyone bad stuff about you for years/months.
And I would make it very well known that you have been putting up with abuse for a while and that you are finally free of that. If you don’t stand up for yourself, nobody else is going to.
Your mistake was marrying a woman like that in the first place. A man’s role is to be a man, and no man is going to get married to a woman who treats him like dirt.
