Contact is a couple - how to separate out into two first names last names

Hi, I’ve looked in other threads, but I can’t see anyone who has the issue that I have. My contacts are households (say husband and wife) and are not separated into two separate contacts. Is there a way to break out first name and last name for EACH spouse (sometimes they have different last names)? We separate the names like this:

John & Sarah Deluce
Sasha James & Adam Carsen
