You need to tell more details of how you have things set up.
1. How are your wife's messages related to what you mark on your phone? Are you using the
same e-mail account?
2. By looking at your older posts, I see that in 2015, you were using Verizon e-mail account. Are you still using that? Then, AFAIK, you are limited to POP3 connection (as opposed to IMAP).
Am I correct? Is that how your account is set in Aquamail?
If I understood you correctly, you are referring to the situation when
you mark all messages read, but when your wife's phone does the sync, they show as unread.
If so, - please read the FAQ item "Why are messages loaded using POP3 not marked as read on the server?"
