I have name changed. I really need some help trying to establish the problems I have with my DM and what to do next. This is long, sorry.
In a nutshell my DM has always had what I can only describe as a chip on her shoulder, she has never been happy with her lot even though she by all accounts has had a pretty good life. This manifests itself with her having an argument with my DF (although usually the argument is only perceived) and then a period of anything from a few weeks to months of ignoring him and usually me and my DB.
The latest incident occurred as she told my Dad she didn't want to go out on NYE, fine, she then said (after 4 days of ignoring him) that she did and he should have insisted, this is a typical trigger. She has now not spoken to my Dad, me or my DB since. I have two small DC's (the eldest of whome loves their granny) she has not even texted to ask after them. I have called her but she grunted at me a few time, barely spoke then I gave up and said my goodbyes, that was the 4th January, nada since.
This is not unusual and this type of behaviour to be honest ruined my childhood, I don't know why but this time I feel thoroughly wrung out with it and like I just want to go no contact. She has some mental health problems I'm sure but also feel like this has become a 'habit' for her and I don't feel like I want to continue to feed it by pretending nothing's happened when she decides she's ok again.
I don't know what goes through her head or how she justifies this behaviour, she has suffered with anxiety and had some CBT a few years ago which she seemed positive about and did seem to help for a time.
As I said the 'arguments' tend to be centred around my Dad but not always it just needs to be someone, it almost feels like she's spoiling for a fight and desperate to find anyone who has wronged her. We had a big heart to heart a few years back when I voiced a lot of this and I think she was shocked with the level of clarity I remembered certain incidents right back to childhood, again I think this resonated for a while but now she's back to same old same old.
Sorry for the ramble, any advice or experience would be helpful as I really am at a loss of where to go from here.
