Would you get a joint bank account if not married?

My boyfriend and I have a shared phone bill but we want to get our own place so planning on putting the money together to see how much we make a month and also so I can help with the phone bill and save up together for stuff. But I’m kind of iffy because I’m old fashioned and think that should only be if you’re married we talk about engagement and all but hasn’t happened yet. Opinions! Also please don’t tell me not to do it, I wanted your opinions not telling me to change my mind thanks!
