Bottom line is that women invariably carry the burden of raising children financially and otherwise if there is a split and men want to be BMD ....a bare minimum dad, like your Ex.
It is why some women are very careful and protective of who and when they have children, as they know ultimately they will be responsible for their children and that will hugely restrict them in their ability to juggle everything.
Financially, pension wise, women usually bear the brunt of the decision to go ahead with a pregnancy.
Unfortunately so many do NOT look beyond delivering the baby and find a relationship breakdown so shocking, as the reality of how single parenting will impact their ability to work hits them.
I think if most women fully educated themselves it would give them deep pause.
I also think that schools could really help in this area to explain the Math of having children to young women.
As mothers we definitely can have the conversation with our daughters too.
A friend of mine has a daughter that found herself in this situation, .......that she couldn't continue her primary teaching job with the logistics of her young child after her relationship broke down.
She hadn't been with her partner long, 18 months when she became pregnant and decided to go ahead with the pregnancy...at 28.....despite her parents explicitly warning her of the pitfalls.
The relationship fell apart 12 months on, and suddenly her daughter is looking to mum and dad to be her child minder as her ex has taken a new job an hour away and is a BMD.
My friend and her husband were both only 12 months retired, and had zero interest in child minding a baby fulltime.
They are actually very pissed off with this turn of events as they had tried to talk to their daughter at the time, but she was having none of it.
She has had a very rude awakening as to the consequences of her decision.
They decided to help financially with the cost of childcare rather than do it themselves as they want to enjoy their retirement.
They reared and put all their children through university whilst working full-time and had really looked forward to plans they had made.
Life is now very different for their daughter juggling work, a childminder and parenthood alone.
She loves her little boy as do her family, but the responsibility to make it work is on HER, and my friend has said that if she had her time over she has no doubt she would make a very different choice.
My friend has huge sympathy for her daughter, but after nearly 40 years of working, rearing her own children, educating them, making sacrifices for them, she and her husband want to enjoy their good health and retirement while they have it.
Not unreasonable IMO.
My friends that are recently retired/retiring soon, have spelt out very clearly to their children that child minding will not figure in their retirement if their children choose to have children.
This is a great conversation to have prior to your children procreating so expectations are clear.
Emergency help of course, but regular childcare....absolutely not.
