That said, when I started working part time, I expected that her father would compensate, but that never happened. He has lived his life without compromising and when we both retire I’ll be poor and he won’t be
Whatever the reasons why he didn't compensate, you still made the choice to go PT.
I am an example of a single mum (when children were 3 years old and 18 months) with no help from family at all (single child, parents living abroad) not their dad who only saw them every Saturday during the day, and I made it work. My choices were to work FT, and took 4 promotions over the next 20 years. My children were in nursery and then before and after school clubs, usually 8 to 5:30. They were alone to get up in the mornings and get to school from the age of 10 and same after-school. It was the only option.
They are now in their 20s. Both excelled at school, went to Uni, and are now both working in very good jobs. I am very close to them. I asked them a few times if they would have liked a different childhood and they have both said no. They said that my focusing on my career meant that there was money for them to have many opportunities. They did activities, we went on nice holidays, they went on school trips. We lived in a nice neighborhood and they went to good schools.
Our time together was reduced in time compared to many but not in quality because it was special.
I fully get that this is far from easy, and indeed, I found it very hard at a number of stages (mainly when facing redundancies), but the point is that it is not impossible and many other women do manage it as well and better.
It really really does come
to choice.
