The most likely reason for that is that they are failing VM's authentication checks that ensure the email has not been sent by a scammer.
Automated email responses such as automated transactional emails, like those you describe, often fail VM's checks because of discrepancies in the way the sending organisation's email software has been setup. VM thinks that the sender's email address has been spoofed (faked). That's been reported here many times. There is no way you can get round it except to switch to using an email account from one of the dedicated email providers. (See the link below)
"Is there anyway to split this account or delete one email account from this to create a single one in my name only?"
If emails sent to your wife's email "hername" address are also appearing in your "myname" email account it would seem that your wife's email address is not actually a separate email account but merely an alias address for your email account,
The ability to set up alias addresses was a feature of the Blueyonder email service.
So it may seem strange but at the moment there is actually only one email account - that's your "myname" account but it has two email addresses, "myname" and "hername".
There is no way to make the "hername" address into a standalone email account.

"..or an easy way to change my email address logged with hundreds of people and businesses?"
Sorry, the only way is to work though them one by one.
I hope that all helps a bit.
