To be surprised at this?

Just felt she would have forgotten and moved on as we all have.
A year ago DH and I went through a bad patch. He ended up moving out after a while as we were worried the arguments would impact on the kids. Because of this, I employed a housekeeper/sitter. I saw her everyday of course and kids did too. Very reliable etc. All was good but she then started saying the kids were misbehaving and I wasn't seeing the same when I was with them so there were some issues there and then my car got a bump on it and she felt I was accusing her (she used to borrow it but wasn't even there the day it happened yet she felt I was blaming her). So in the end she quit on the spot. It ended badly but life goes on and it was sad but within the month we as a family had moved on from it and DH moved back in.
Anyway. Today I received a letter from her saying how difficult she was finding it to move on, how she still thinks about the situation most days and gets upset about it and that she wants to speak with me to clear the air. Aibu to say I would rather not?

I don't understand quite what she wants to achieve?

I’d be wary of getting drawn into her drama. It’s quite odd that she assumed you were accusing her and is still ruminating on it after such a long time.

I’d maybe reply saying that your family appreciated her help at the time, that to be clear you never suspected she was responsible for the bump to the car and that you hope she has now found a role she is happier in.

but make clear that you’re not interested in meeting/discussing. Then any further contact I’d probably just repeat that there are no hard feelings on your side and no need to meet.

No. She sounds deeply insecure and needy and it would be sheer folly to stir it lol up again.
Politely tell her there’s no need and wish her well. Finito.

Does she know your DHis back? Does she hope to get her job back?

No she wouldn't know about that.
I posted on MN a few months ago about the car situation and was ripped apart on here saying that I was lucky she hadn't left due to my handling of it so not sure what to think. The main thing I get is that she didn't feel trusted and appreciated which is why she went but still cares for us, feels bad it ended badly and wants to meet to resolve that but as you have all said, that's just pointless. I get it might make her feel better in herself but not right for me.

I would either ignore it, or reply saying that you don’t see any need to meet, and to wish her well for the future. Don’t get drawn into anything that may or may not have happened.

Nothing did happen with the car, I know that.
Just don't see the point in meeting. Even if I saw her in the street I wouldn't stop and say anything because it's awkward and things were left that way but that is life.

Probably figured out by now that the job was a cushy number and wants it back.

Or maybe wants to use you as a reference for a new job.

Are you downplaying the car incident now if when you've previously posted about it everyone felt sorry for her?

I've described it as I did above.
I said to her it had a substantial bump on the side and wasn't sure how it had happened and she felt I was blaming her for it. Everyone jumped on me saying how I was lucky she hadn't left immediately and how badly I handled it. Yet here I am being told different!
To be honest, that was only one thing anyway and not even something she really mentioned in the note, it was a series of things really, that being just one of them I guess.
