I’ve had ten years of paying for everything for three kids. After repeatedly asking, he has now asked for a breakdown of what I spend.
I thought maybe an app or a shared spreadsheet so I can update it with what I spend, and then take off the odd £50 a year he gives towards them, might be a good illustration of how little he is contributing. Any recommendations gratefully accepted for a user-friendly app, especially if I can share it with his new partner too, as she is far more engaged and willing to see that he should pay something than he is.
