No ! Just because they treat you like a shit doesn't mean you have to put energy on the same game they're playing showing you' re not as different as they are, don't do that ! People of that kind are just building their way to a place maybe you can build too, but you really wanna be part of that? Is useless
I truly have witnessed a narcissist change some of their behaviors after years of standing ground. It's a very slow and painful process. Doesn't mean it's a happy ending but it does give hope to others enduring the hell. The more one recognizes and stands their ground and gains strength; the better the chances of a healthy outcome. Some narcissists are so damaged internally, they just need love, patience and guidance. But not enabling. (Of course this is not true for all cases).
