Ben Platt dumped Noah Galvin in the early days of their romance because he was worried they would "ruin" their friendship.
The Broadway stars got engaged in November 2022 and the Tony Award-winning actor has recalled how they started "hooking up" in 2019 while workshopping the musical 'Alice by Heart', only for him to "panic" about the future.
Speaking to Jesse Tyler Ferguson on his 'Dinner's On Me' podcast, Ben said: "We would go to the stairwell during break and make out in the stairwell."

But after a few months, Ben "panicked" and sent Noah a "text that's so long that it has an arrow at the bottom to go to the rest of it."
He recalled: "I sent him a dissertation, and it was like, 'Oh, feel like we're gonna be friends for our whole lives,' and like, 'I'm, I'm worried if we jump into something, it's gonna ruin our chance to be friends.' "
He ultimately declared he wanted them to just be friends, leaving Noah unimpressed as he told him "I hate you".
But Ben admitted: "Basically, now I can tell in hindsight, like, [I] met someone who, like, actually we saw each other and it freaked me out."
The pair - who first met in 2015 through mutual pals - retained a friendship for some time and occasionally ran into one another at events before things eventually turned romantic again.
The 'Book of Mormon' star recently discussed his wedding plans and admitted his only concern is to keep people dancing.
He told People magazine: “For me, the only real judge of how the vibe is how many people are on the dancefloor.
“We’re going to have a band at one point and a DJ at a different point. So that’s my focus. I’m not someone who needs to focus on the place settings like, beyond food, I’m chilling."
Ben previously admitted he and Noah had "skated around" getting into a relationship for a long time.
He told Kelly Clarkson: “We were friends for five years, and right before the pandemic, we finally decided to really give it a shot.
“We kind of skated around it for a long time.”
The actor added in an interview with Out magazine he had finally found a partner “that I really love”.
He said: “(Noah) has a really unique ability to help me to… be present where I am and to make the life that’s happening day to day too wonderful to not want to be on the ground for it.”
