You don't give enough information about what you mean by "Domestic Partner" or what state you live in. But, if you are not married, you can't get divorced because there is no "marriage" to dissolve. If you live in a state that has some sort of legally recognized "Domestic Partnership", you need to consult a lawyer in that state to determine the requirements for terminating the relationship.
