<human>: So it was her grandmother's funeral yesterday. She was close-ish, but stable enough that she only cried once during the funeral and was her normal self for the rest of the day.

On the drive back we are randomly chatting and bring up the "shit things about each other" topic, which I take a little too far, which causes the first level of upset-ness (which she later puts down to the funeral). We don't really talk for the rest of the journey.

If things had stopped here we would've been fine, however I keep digging a hole for myself. One of the things I mentioned was that she gets emotional too easily. So during a phonecall late at night afterwards she is saying I picked a shitty day to have a go at her, and that it's only because of the funeral that she got so upset. I then say I'm not sure that's true; I think she would've reacted in the same way, and is just "playing the funeral card".

Now this last phrase is the a-bomb. She gets crazy-upset, says it's over, and hangs up. No contact a day since.

So I now feel 1) really bad for making her upset 2) really stupid for saying such a tactless thing.

I'm pretty sure I want to mend this, but am not sure how to go about it.

Can you provide a brief overview of the text?
<bot>: GF mad cause I said I thought her story that she was only upset because the a funeral was bs, she went mental, she's ended it. What should I do to try and repair this?
