Adding Spouse on Online Family

I invited my spouse and it sent the e-mail to her, but it gives the message that the invite has already been accepted. She was in the process of setting herself up when it was sent to her. We stopped that setup and tried to do the invite, but it said that there already was an account at that e-mail. Now we can’t proceed. She doesn’t have another e-mail to send the request to. How do we fix this?
