Mark,
Is it possible for you to "disconnect" from what he says? It doesn't sound like he will ever change, and meanwhile you need to find a way to relate to him that doesn't keep devalidating and disempowering you. Either that or...just don't see him any longer? Are there other choices? Apart from the present situation where you are being battered all the time?
Much love,
Larry
