As said above, this would be easily solved if more men were willing to genuinely take on 50/50 care but they rarely are, either during or after a relationship
even this isn’t practical.
dh genuinely did 50:50. Not a high earner but flexi hours so did school runs, bedtimes etc. his mum did all pre school childcare so she could work.
when his ex had an affair and manipulated him into leaving, he had nowhere to go except his mums one bed flat.
so even if he’d wanted to continue 50:50, no where to sleep, no space for toys, no garden etc.
when the divorce went through she’d “disappeared” 15k of joint savings, and there was barely any equity in the house. So he got nothing, she kept the house and car.
so there he was, paying his mum board, having to pay to take his kids out when he saw them, having to buy a car to do so, paying cms. He didn’t have enough disposable income to rent anywhere other than a shared house.
so again, if one household won’t split to provide two adequate living arrangements, how does 50:50 work?
