Couple things, wfm.

First, there is the possibility that your H is MLC. That said, he will NOT remember some of the things that happened, which lead to your current sitch.

That said, even if he is NOT MLC, people have their own specific understanding of things that happen. He may truly believe he never asked you to leave.

In my mind, I seem to remember that my stbx DID NOT ask me to leave. I chose to leave and she alluded that I did not have to. I'd put bets now, that she would tell people she DID ask me to leave. Although that's a bet I could just as easily lose.

The point is, it really doesn't change the sitch as it currently IS. All it does is harp on an unhelpful dialogue of who is "right" and who is "wrong".

For you, the question is: Why did you have a conversation about toothpaste when you simply could have gone out and got some?

This isn't about "how" you asked him.

You could have been all pleasant and said, "hey, hon... I realize I am running out of toothpaste and will have to go to the store to get some, unless you have some extra at the house that I could have."

This is about an item that might cost $6 if you bought the value pack at Costco of four tubes, plus a toothbrush.

I have a feeling, under all the pleasantness of your "ask", you were letting your H know how much this separation has inconvenienced you to have to grab a tube while you are at the store getting other necessities and that your world would be so much different if you were still living at the house.

I do say that with tongue in cheek. And I DO understand that you are still frustrated and angry with him. If that were not the case, then you would not need to keep proving that he's an idiot.
