Hi Tabby good to see you back in. Also very glad that your daughters can see what is happening. As it gets to the point where you find it hard to trust your own judgement - you have some back up.
"He just says I’m being paranoid or over reacting". If you read up the thread to 8.53 this morning you will see I have written of how it sounds your partner is "operating",
*denial he did or said what he did - ie, saying your idea of reality was actually wrong/didnt exist/he'd never done or said it (gaslighting)
or - it was my fault that he had said/done such and such because I was ill or mad*
With my Ex I came to realise that he could not bear to take responsibility for any criticism or blame.
( I have pages of WhatSapps and a number of round recordings he sent to me bitterly blaming his brother, his mother, me, in great detail.)
Now - I have of course examined how I was, what I did, and can see looking back how this or that or the way I was might have contributed to a whole range of situations. He was -is -not capable of doing that (and being a depressive, I tend to blame me anyway)
- its a facet of people who have narcisistic disorders (of varying degree of course, from covert to very upfront, where control extends to looking at your mobile and opening letters etc)
that they need to blame, as opposed to two people being able to sit down and discuss "look, our relationship is dysfunctional".
This is all in retrospect, of course.
At the time, Tabby, it was a matter of survival, pure and simple. And no way could I have done it alone. I got MH and Domestic Abuse and in my case some police support. (dont let that put you off, btw, it was circumstance driven to reach that point, and others writing here have not involved police)
But right now you need to make that phone call to Domestic Abuse, ad that appointment for your GP (providing you trust them reasonably enough).
