Thoughts on joint account with bf

My boyfriend wants to have a joint account.

He sees it as a good saving opportunity

But I just don’t know if I’m fully comfortable with the idea of closing our separate accounts, I’ve had my account for years and I have an emotional connection with it, my first bank account I got when I started working years ago and I don’t know if I’m ready to close. I have talked to him about it and he has said that it’s a stupid reason, he knows I have a shopping problem and he makes way more money then me (he gets paid weekly, I get paid twice a month and only get paid $1k each check while he gets paid $2-8k each week)

What are y’all thoughts about joint accounts with boyfriends? We have been together for five years (not married yet)
