How to get my MARRIED sims to move into the same house in the Sims Freeplay for an iphone 5C?

So I have been playing the Sims Freeplay and I have a newly wedded couple. I really want them to move in together but it doesn't show that as an option. I know there's an option for that when they are "Partners" but I forgot to click that when that was their relationship status. Is there a way to get my Sims to move in with each other without making them divorce and then love each other again until they are partners?

There should be an option when you click on them
