My MIL, with whom my DW and I live, has PTSD (diagnosed), anorexia (undiagnosed, and not acknowledged by her - nevertheless, she has osteoporosis, hyponatraemia and BMI <16) and possibly the most advanced martyr complex I have ever seen in anyone. She is in her late sixties. She is dependent on FIL, and he is dependent on her: nevertheless, they cannot stand one another and their relationship reflects that. DW and MIL say that FIL has in the past been very controlling, to the extent of being psychologically abusive. Our presence in the house has moderated FIL's controlling behaviour to a significant extent: he has been OK since we got there. The problem is that my DW (who is very heavily pregnant) and I are finding it increasingly difficult to deal with MIL in an empathetic and tactful way. My reserves of patience are notable, but they have almost run out: she is starting to show some seriously bad emotionally abusive behaviours herself (horrific personal insults/crying fits followed by grovelling apologies, once or twice a day). I have started calling her on it, because I am not prepared to have my wife insulted. I'd like for us to move out at the first opportunity, but there won't be one for a while. DW is also planning some kind of group therapy involving her, MIL and SIL once the baby comes. In the meantime, I'm struggling to find any good resources online, so can any of you direct me/us towards some good ones please? Your help would be much appreciated because I'm struggling to keep it together here!
