I would be interested when that was, because I agree with noodlezoodle that to my knowledge, she has never said this. A few times posters have suggested she had told Harrison and I actually double checked and posted what she actually said at that time.
Hence the repeated comment that we may logically assume she would have had an abortion, but not wanting a pregnancy (or even being relieved at a miscarriage - which I assume, but I don’t think she has even said that) is a different decision from terminating a viable pregnancy. So we just don’t know definitively.
The nearest she has got to telling Harrison anything like this is in the early days when she dismisses it as a miscarriage and tells him it was just a few cells (which I recall quite clearly). I was even hoping she would explain to him then but she did not say anything about abortion or even being glad she miscarried or even (as far as I recall) not wanting the baby. She really needs to shake Harrison out of his dream world. However as I said a long time ago I think they both know the truth of how each other feels but it is so incompatible that they do not want to address it, because they know it will likely end their relationship.
She has repeatedly told him there was no baby, it was a miscarriage, up until recently mocking him for it being referred to as a baby in the prayers. He even then agreed, not literally, but it was about what could have been.
The truth and the problem is they are unable to sit down and calmly discuss each others feelings, beliefs and where they go from here but hopefully now since Fallon told Kirsty
‘Been doing a lot of thinking, I really need to sort things out with Harrison’
They might do that, it is such a shame on the whole they are both decent, kindly people who love(d) each other very much, but this accidental pregnancy and miscarriage has just dragged all Harrison’s desires to have children out of the box he had tucked them neatly away in.
