I hope it's OK to post on here, although it's regarding my PIL, especially MIL. My own parents died when I was a teenager and I had a very positive relationship with my mum. Emotionally she was very healthy and strong and I realised after she died that many of her own friends and family lent on her a lot for support. Although I was only 13 when she died she had given me a strong sense of self and also a good understanding of boundaries (although for a long time I could not have articulated that concept).
We are living a very long way from my MIL - she is across an ocean, although we did live closer five years ago. In many ways she seems to have positive qualities and I can enjoy being around her - she has a GSOH and can be kind. There has also been a lot of volatility in how she relates to just about everyone. I can't really say she is Narcisscistic but I would say she is immature and erratic. She also definitely sees my DH as the Golden Child and he has fulfilled his promise by attaining a prestigious education and career. DH has one younger sister and I could never quite understand the role she plays in the family as she (at least publically) is almost always passive "happy" and compliant. My MIL talks quite openly about how her expectations for SIL were low - she definitely didn't see her as ordained from on high in the way DH is in her eyes. More recently I feel like my SIL is expected to be the rescuer of her mum.
I noticed this quite early on. We had only been married a few weeks and I was hanging out with MIL and SIl and MIL was spouting on and on about DH. I listened and then said "MIL you are so right because DH, he.is.a. GOD!" and to her credit MIL fell about laughing as did SIL.
Over the 17 years of our marriage MIL has lurched from one crisis to the next (PIL are divorced) usually involving money as she immediately spends any money she has access to (so all credit cards will be maxed out as well). She would absolutely love DH and I to take full responsiblity for her - which we won't. It's like she wants someone else to be the grown up or parent. When I'm with her I feel as if I am in this super sober, stoic role and she sees me as a complete stick in the mud. It is not constant but over the years there have been a number of times when I have been devastated by her behavior towards me. She opened letters I sent to DH when we were engaged and read them out to friends and family members. She screamed down the phone at me when our second DD was having chemotherapy as a baby and I was all alone with DD in the hospital room. DD was severely anemic and the same colour as the white bed sheet. MIL called me crying and I tried to comfort her saying "It will be all right". She then started screaming at me "It won't be alright! It won't be alright!" I think that is officially up there as one of the worst experiences of my life. She screamed at me chasing me around the house when I was pregnant with DC # 4. This was beacuse she turned up unannounced at 7:30am when I was trying to get DCs ages 6, 4 and 1 ready for the day and then she said something quite cutting and cruel to me. I felt hurt for a few minutes and then thought "I'm not letting her get away with that" and said calmly that I thought what she said was unkind. She completely lost it and I had to lock myself in the bathroom to get away from her.
She will claim she never remembers these times, she also never apologizes. I haven't even lived near her for five years but I do not know what to make of her. I have the impression that all family issues if possible will be blamed on me, I knows she definitely blamed SIL's husband and told outrageous lies about him - they are now divorced. Her "lies" are not really lies but more stories, she comes out with the most bizarre reason why she thinks people do things and sincerely believes them. It's like her sense of reality is off kilter.
This is very rambley but I feel like I always have to protect myself from her. I think she would manipulate me if she could - but she can't.
I want to be fair to her, she has raised two lovely human beings and I know I have my failings. I just feel she would engulf us if we let her
