To those who live with their partner, how do you split expenses and have savings?

Currently a year and a few months into the relationship and I moved in with my partner because he has a better condo unit.

I wanted to ask how everyone usually splits the common expenses such as electricity, internet, water, condo dues, plus gas.

If your partner makes more (almost double) your income, does he shoulder most of the expenses?

I was thinking that we open a joint account to have a pool of money wherein we can take common expenses from including food, dates, or even travel.

What bank would you suggest is best to have a joint account in? Would a digital bank (such as CIMB, Seabank, etc) be advisable? If so, do they provide an ATM/debit card? An issue I thought would be the costs of withdrawing/transferring in the event we need the money.

Do you have your own savings even after joining bank accounts?

Edit: Did not know my queries would garner a lot of engagement. I really appreciate all the opinions. My parents never really taught me these things so I am still trying to adult as a 30-year-old girlie. Kaya ko naman mabuhay on my own but living with someone is a whole new ballpark. Please be kind in the comments. This is a safe space for people to discuss and/or disagree with your opinions. If it doesn’t work for you, don’t follow it. I’m also siphoning through all of it and do what applies to my situation. ☺️☺️☺️
