Agreed. I’d say Helena was far from stupid, in fact she always gave the impression of being well read and well educated. From what I’ve read, which is quite a lot, I think MH was very attracted to PY but grew tired of her and all the drama associated with her and her life. Obviously by that point PY was pregnant/had given birth so he felt unable to end the relationship. It’s well documented that PY was utterly besotted with him.
