Is it not his money? Does he not control the account? Well then that is a different issue. Technically, you should just let him burn it. The money is still in whatever account issued the check, so you should be able to just call them, explain what happened and they will just issue you the money in the form of another check. They’ll probably just give you a lecture about how silly it was to just let a $5,000 check lay around without depositing it into a bank you control. Even then, you have a clear case of vandalism at the least or grand larceny at the most. So you actually have some options if the money doesn’t belong to him, legally speaking. There is such as thing as pro bono lawyers ( Pro Bono means they work for free for needy people. They won’t teach you that definition in Literature class.)
Second, your question and the question details differ drastically. So drastically, I’m willing to call this question disingenuous. In one you say that your father is trying to bully you into changing your beliefs. In other, you say he doesn’t want you taking a certain major. Not the same thing. Context matters. You haven’t broken up. He just now has freedom to sleep with others, etc because he can say he’s “”not with anyone”. Stop sleeping with him and truly break up with him. Get out of this nightmare. He is abusive, controlling and sees you as his property. He doesn’t have the right to control how you dress nor demand that you have no male friends. You don’t want to live this way, do you? Its demeaning and archaic. You aren’t his property.
