John and Caitlin's relationship timeline

In John's memoir titled, If You Would Have Told Me: A Memoir, the actor admitted he had a "crush" on his co-star.
He revealed to People: "She was in another relationship. And we just met back up again. Her roommate was on an episode of Fuller House, and so she was in the audience. I walked in, I went, 'Hey, are you stalking me?' She was like, 'No.' That's why I love her. She's like, 'What? No. I haven't thought of you twice.'"

In 2017, John proposed to Caitlin in Disneyland and they tied the knot the following year in Studio City, California.
That same year, they welcomed Billy into the world.
What has John said about Caitlin?

He revealed to People in 2021: "I wasn't deserving of it yet I think. But six years ago, I sobered up and I became a better person. And when Caitlin came around, I recognized it immediately. I said, 'I have to be good for that to make it work.'"
The star revealed what the secret to their successful relationship is, expressing: "I forget what the magic ratio is, but I think it's about having more positive reactions over negative. It's nice to connect over something else — it's not always about the kid. We're still trying to find the balance!"
