Lots of people here are saying it is a trap, you have no choice, it will pass once they grow up, etc.
We are overlooking, or not wanting to look, at the choice some mothers do make: the choice to leave.
Either leaving for good and vanishing, or doing a "Disney mum" and seeing their DC every other weekend whilst they live with their dad.
Every mother has the choice to leave.
Even mothers with severely disabled DC, or single parents can take that choice - but there is an almighty battle to be had with social services first, to get the children taken away.
Or there is the choice to risk being charged with abandonment and prosecuted - it is still a choice that can be made if the alternative feels worse.
But it is easier to say "I have no choice".
This is the huge taboo.
This is what we gasp in horror at, can't bear to think about.
This is what we abhor in women, and denounce and vilify women for - leaving their children.
I find the contrast with society's attitude to men who leave to be sickening.
It is deemed unforgivable for a mother to tell her child, or to demonstrate by her actions, that she regrets having them. But fathers do it with barely a murmur of disapproval.
