relative terminology

What do you call a mother of your partner if you have a de facto relationship?
If you were married, that would be a mother-in-law, is it the same if you are not married?
How about 'the enemy'? or maybe you are new to this?

Just kidding - technically she is not your relative. you could call her your defacto mother outlaw.
"The outlaws" suits every circumstance. No need to change terminology if you become hitched. Even in divorce, they become the "ex-outlaws".
