Did VPR Keep Them Together?

On the latest bonus episode of HOTM, I broke down the relationship between Tom and Katie, who as of last night officially announced they are divorcing. And now I am wondering, they were only together because of the show right? And not in the sense of they only married for TV, but that the show was the glue that kept them together longer than they would've been. Because look at the other cast members, Raquel and James broke up right before they filmed the reunion. I would say something about Lala and Randall but that was clearly not a relationship heavily featured on the show and he was caught cheating, so the circumstances were different.

But I have to know your thoughts, do you think the show kept them together? Is this in Kyle and Amanda's future? Or anyone who chooses to get married on camera?
