lying partner

What do you do when your partner continuously lies to you and you know they are lying to your face and you call them out but they just keep lying? Then they turn around and call you crazy, psycho, etc? Or they leave when you call them out on their lies hoping you will forget about it or get over it to the point where you feel like there is no point in bringing it up anymore? Not to mention the lies are over stupid crap too. Half of them are not even worth lying about?
