I don't want to know too much about the causes of your family conflicts, but I can see from your words that you are not good at communicating with people. Maybe your father thought you lost money because of your mother or her family, but you didn't explain it clearly. You may not have a good relationship with your stepmother at ordinary times, which you need to pay attention to. You should make some appropriate improvement efforts and don't be hostile. Maybe I misunderstood you, but in any case, I don't approve of your breaking up with your father! Never agree. At least it's impolite of you to do so. You will regret it later, and society will have a bad opinion of you.

Suggestion: deal with it coldly and let time deal with family conflicts.
