Please Help, I am Married to My Mom

Don't ask how it happened, but I am married to my mother.

Marriage is a social union or legal contract between people that creates kinship. It is an institution in which interpersonal relationships, depending on the culture or subculture in which it is found. Such a union, often formalized via a wedding ceremony, may also be called matrimony.

I am currently in a binding contract with her.

I am about to cancel the contract.

How do I tell her nicely to fuck off?
