Money and relationship

[Dolly2288]

Me and partner have had a rough few years but only recently I’ve sort of come to the realisation I’m a mug. He earns more than me yet we go 50/50 on all bills, I work full time and so does he and looks after businesses he has, I sort all childcare, cooking, cleaning.
how did anyone sort finances? Everytime I try to bring it up he just shuts it down, I’m really considering calling it a day he’s like a child, and I wouldn’t want my child to end up with someone so selfish like him

Indeed call it a day and firm up plans to separate from him. He’s taken you for a fool for far too long and has feathered his nest at your overall expense.

You’re not married so 50:50 may be reasonable but he should then definitely be picking up half of the domestic and parenting stuff. Otherwise you’re giving your time for free.
Not surprising he won’t discuss it. Why would he want to change it? You have put yourself in a vulnerable position by not being married as you could end up with a split where he goes off with his share of assets and a better pension /earning capability after you’ve spent your life facilitating this. Good that you’ve realised this.
