So... DP's mother invited herself for Christmas. I have posted a couple of times (under different names - her issues are so distinctive that even reading two or three could ID us) about DP's Mum and how badly this has affected him. In a nutshell she is emotionally/psychologically abusive. I don't want to out us so won't give specifics. She has also invited herself to stay for Christmas and arrives tomorrow. I will only be here until just before Christmas (long-standing commitment with my family, DP was also invited but a) we can't house his Mum as well, b) he never wants them to meet and c) I told DSis what she was like and DSis said if she was going, DSis wasn't). I have arranged a full itinerary and ironed out every conceivable problem I can think of.
DP won't cut her off (I suggested, after a particularly bad episode, that he should just stop contact but he says she'll just hassle him. He also feels bad because she has isolated herself from both sides of their family and his Dad died not so long ago).
Does anyone know the best way to support DP through this please? The problem arises, aside from the mental damage she does, in that his coping mechanism is something that will cause him long-term problems (not drugs) and something that I hate. He didn't do it when we got together but I have found out since that every time she speaks to him/sees him, he drifts back (started up again after his Dad died). I don't want to say what it is because I posted before (a while ago, different forum) and the thread became about my dislike of it, rather than how to help him overcome it. He is a smart man, knows it's damaging but has done it for so long in response to her (he's 41) that it seems to be instinctive.
I feel like a bitch because she is a vile woman and I don't blame him for wanting to do it but OTOH I, selfishly, want him around for a few more years! I also feel that if I somehow found the 'magic'/a better emotionally supportive response he wouldn't need to do it. This is so weird for me to comprehend, though I think/hope I am better at helping him now: I come from a very close and loving family and had a hard time believing that anyone could treat their child in this blatant, OTT way (not the abuse as such, but the way she does it).
I'd also like to use this thread to come and have a vent over the next few days. My closest friend, also DP's closest friend, who knows what is going on (he is v private) is going back home so I can't talk to anyone IRL without breaking his need for privacy. TBH I wouldn't want to talk about it IRL - the things she does are so outlandish even our friend had a hard time reconciling it with the sweet old lady she presents as publicly.
I think maybe I'm asking for some ears when she does get here and some links/recommendations for things I (and maybe DP, although he's not much of a reader - I would have to read out loud to him) could read to help me/us understand how to cope with her please.
