Oh this is indeed heartbreaking.
I don't think the media are to blame for this idea that it is a simple matter to get pregnant when you are late thirties and beyond, and any articles I have seen about egg freezing are about how difficult it is and how it should not be seen as a surefire way of enabling older women to have babies.
Everyone - surely - knows that fertility falls off a cliff after about 35, and despite the success stories we hear about, it's actually very unusual for a woman to have a baby at forty or more. But knowing this, and accepting that it actually means it applies in real life, is not happening, to all of them. Somehow, today's otherwise intelligent women have got themselves into a state of denial - not helped by the way the world of work expects people to be making career advancements in their thirties.
Silverlining your poor dd may have just assumed this man would be ok with a baby, or perhaps didn't dare raise it in case the answer was 'no'. She has to think long and hard about her future, with him or without him.
