Wife is very toxic abusive manipulative from 10 years

My wife does not allow me to work outside the home. She constantly makes calls, levels false accusations, and blames me for everything. She can involve anyone—her sister, landlords, or anyone she can use—to manipulate or abuse me. If I am away from home for more than an hour, she becomes extremely angry and exhibits bad behavior toward the children.

I discovered that her brother is heavily involved behind the scenes, supporting and encouraging her behavior. She takes monthly expenses and then criticizes me, claiming that I do not provide enough. These disputes happen daily, and I am seeking help.

If separation occurs, I want to secure custody of all five of my children.
