Advice please, abusive partner

[Hcwxxx]

My partner (m46) has started gaslighting me.
I shall give a few examples, last night everything was fine, watching tv then he said
him - I need to go out in a minute to get some dog food from my mate for the dogs to try (his dogs)
me - oh ok what food is it?
him - wtf, why can’t you just say ok, why get funny because I’m going out for 5 mins
me - I wasn’t I only asked about what type of dog food
him - no I know exactly what you’re implying, if you don’t believe me come with me
me - I don’t want to come I literally just asked about dog food
him - it’s abuse what you’re doing, you shouldn’t question it.

so I left it at that. Later in the evening he brought it up again and changed it to me saying I asked why he had to go out, where etc. which I definitely did not. He would not accept I didn’t say it and told me again I’m being abusive and Controlling.

this is becoming more and more the same thing. I am in conversation with him then he tells me I’ve said something different, it feels like just to cause arguements
later that evening I was replying to my son through text and he said I was licking my lips and was clearly texting another man, I showed him the message and he still disagreed and accused me of deleting.

I can’t move out for a while, but what I’m asking if anyone else has gone through this what’s the best way to deal with it

hes a massive overthinker and believes he is good at reading people and never ever wrong.

My first instinct is that he is lying, paranoid and overly suspicious because he is up to no good..

My ex-h would do similar, it was to cause an argument so he could storm out and get drunk in the pub. Later on he just did it out of habit or to torment me. His ranged from the ridiculous ( you embarrassed me last night at work’s do, you were so drunk —- no, I was cold stone sober as I was driving) to the downright dangerous ( X ( my TA) has told Y you are horrible to the kids and scream abuse at them. Y is going to report you and X will collaborate story.— it was bollocks but could have had me suspended/ disciplinary)

I’d start putting your ducks in a row to get out asap.

Save, save, save to move out as soon as possible. There’s no reason to date an abuser. Make plans for where you’ll live, do the Freedom Project, how to be an example, to your kids in having high, high standards in behaviour you’ll accept from blokes.
This fucker needs dumped by text. Tell him you’re no longer attracted to him, it’s over, do not contact you again. No need for arguing. Detach and don’t indulge his pathetic nonsense.
