If its to do with any activities on the weekend I check with DP in case he has plans, so he can babysit, or if he wants to come too, or in case he wanted to do something else with just us..during the weekdays I decide for myself and tell DP where we will be (he is a courier driver and likes to stop somewhere and have cuddles with Jae during the day lol)
Money-wise we have our own things... DP pays the bills, I pay for the kids stuff like clothing, nappies/formula etc... but occasionally we will 'borrow' money off each other. Groceries we will write a list together because he has things he uses/eats that I dont and vice versa, so we both do that, although I physically do the shopping by myself.
Household decisions currently go with DP as we live with his father, so he has to then check with his dad about stuff... I hate that...
When it comes to the kids, DP likes having some say in Jae's day-to-day care, even though im the SAHP, but being his first and beloved baby, I humour him

To give him credit, he helps out more with decisions regarding my oldest than B's father does...
So its fairly 50/50 here...
