Why when I try to purchase things it comes up as my husband's email

Hey there! That has to do with the payments account you have set-up, and it's not related to your Candy Crush Saga account.

You need to go into the settings of your payment method account (Google, Apple/iTunes, Amazon, Microsoft, Facebook), and change the payments account into your own.

If you'd like more detailed instructions on how to do so, please let me know which platform of the ones above do you use to play and make your Candy Crush Saga purchase.

Thanks in advance and have a great day!
