So there's a massive back story. I'll try to give a brief summary. DM is a raving narcissist and I've worked very hard to overcome the effects of the physically neglectful and emotionally controlling upbringing she gave me. She is a classic narcissist with no boundaries and no insight into how her behaviour hurts the people around her.
Now DS is on the scene she's obsessed with the idea of moving to the town where we live. Currently she's a 3h drive away. At first DH and I thought this might be good for her as she's getting older, the house she lives in is not double glazed or centrally heated, I have concerns for her health and wellbeing. So her moving to somewhere more modern would be really positive.
However her recent behaviour has been outrageous (again) and I've been ignoring her while I work out what to do. Today she's messaging me about this house which previously she said she didn't want but now apparently is at the offers stage with. We are talking months ago that this house was looked at and discarded. We are talking 2 years worth of me helping her look for houses, spending time talking with her, estate agents, viewings, bank appts etc. I had gone along with this moving house thing because I knew she would never do it, it was all just attention seeking and something to get dramatic about.
If I say to her just fuck off then really that's the end isn't it? The whole pantomime comes to an end.
I don't even know what I'm asking now. I just feel so angry and sad. What can I do?
