The constantly lying mother who has no self-awareness

Today, my mother asked me for the car keys for my step-father's as she claimed she didn't have another set and needed to take the car, as my step-father took her car to run his errands. Of course she was lying, because he has another set of keys, which she could have taken, but she just wanted to take the keys from me legitimately this time, as she thought she would not sneak in my bedroom to look through my handbag to take the keys furtively without my knowledge.

I asked her if she would give me the keys back when she returned and she said she would, but I didn't believe her. I told her, that "I'll believe it when I see it, when you return back to see if you actually are telling me the truth."

Around dinner time, I asked her where the car keys were and her response was: "They're my keys, not yours."  So, basically, I was right, she lied to get the keys from me because I told her I wouldn't be paying for all of the registration costs for a car I don't own.

She just cannot stop lying. And then she has to justify her lies with more lies.

She then told me they "gave" my brother, LayZ boy their old van and as he didn't have enough money (he never does) to register it immediately, he had to do so after three weeks. I asked her how she could use that as an example when my step-father's car is not in my name - it's not my car. She realised she couldn't win with that angle, because there was absolutely no bearing on the discussion, she didn't say anything, probably thinking about what else she could try to justify herself. She continued to tell me I had to pay for registration costs if I wanted to drive it and I continued to tell her to forget about it.

She then went to the sun room, in a rage, to bitch and complain about me to my step-father. And when I told her to stop bitching about me, she proceeds to tell me that, "your step-father asked me why we were arguing and I had to tell him". Again lying. She purposely walked in there to complain about me and she started bitching about me to him, without any prompting from him.

She came back into the kitchen, where I was preparing some vegetables to roast and continued to complain to me about the car. I kept telling her she outright lied to me, then she went to bitch about me behind my back to my step-father to inflame him even more, as she knows he will be nasty and say all sorts of things to me. She didn't like that because of course I was calling her out on her lies.  She also told me I had no right to have the keys - when she gave to them and told me to take them before. Now she decides to rescind that, by lying about it. If she was honest and asked me for the keys honestly, I would give them to her. They're not my keys, it's not my car and I only drive it when I have permission to do so. I don't just forcibly take the keys!

Then, like a nutcase, she tries to put her arms around me and tell me, "mummy still loves you" like I am a recalcitrant 5-year old child that needs pacifying! I told her to leave me alone, that I did not want her touching me when she was just bitching about me less than a minute ago. How insane is this woman! And before I walked out of the room I told her that with a family like mine, I certainly did not need enemies. Her face changed to deep concern when I said that because something must have reached inside through her delusions to make her realise just what a bitch she is being to me.
