I had every sympathy for Richard. She gaslit him and not very well.
She gaslit him? She's scared of him.
And he did say those things multiple times. Just because she can't remember the exact words he used and stumbled to explain the location, while he glared at her with his jaw jutting out (around the firepit, at the retreat, and from memory he bellowed in a self-pitying voice that they weren't fucking), doesn't mean he hasn't repeatedly referred to their sex life publicly, which upsets her, and in terms that specifically upset and embarrassed her.
They are not in their twenties, they have adult children, and they're on tv and he said on the couch: "We gazed, we hugged, we sucked, we fucked."
This upset her, she's explained exactly why. He knows. He's done nothing but sulk and pout since. The experts and her friend gaslit her into thinking it was just her "walls" going back up, and she's been trying to open back up to him, but he's repulsed her, and he is clearly trying to bully her into having sex with him again. Despicable.
