Modern FamilystarSarah HylandandThe Bachelorette‘sWells Adamshappily shared the news oftheir engagementon Tuesday. And even before exchanging vows, they’ve proven their love in sickness and in health.

“He has 100% changed her life,” a source told PEOPLE late last year. “They are very much in love and he is so good to her.”

The 28-year-old actressunderwent a second kidney transplantin September 2017 following a lifelong battle with kidney dysplasia. (Hyland’s first transplant,donated from her father in 2012, failed.)

Hyland met Adams in person for the first time just three days before undergoing the second transplant. (The twobegan flirting on Twitterthat summer during his stint as the bartender inBachelor in Paradise,but Hyland had been vocal about her not-so-secret crush on the radio DJ since his time vying forJoJo Fletcher‘s heart on season 12 ofThe Bachelorettein 2016.)

“He was texting me in the morning before I went into surgery, andwe were FaceTiming the entire timeI was in the hospital,” Hyland toldSELFin December.

Adams, 35, was also around for Hyland’s painful recovery post-transplant.

“He’s seen me at my worst,” she said. “He was there through all of that. I think that’s why I feel the most beautiful in his eyes, because he still finds me beautiful after seeing all that.”

The experience only brought them closer.

“It was a really intimate start to a relationship to have to go through those hurdles at the very, very, very beginning when you’re just even getting to know a person,” she said. “Also, falling in love with someone before you can really be intimate. I did not believe that that was a thing, but it is.”

Hyland — who also hasendometriosis— shared a similar sentiment in April,telling PEOPLEthat she “lean[s]” on Adams.

A sourcetold PEOPLEin December that Hyland is “doing great” overall, though she “still has her hard days.”

“Not only has all of this been physically demanding, but the emotional and mental demands have been just as challenging,” the source said. “She has a chronic illness and she will have to deal with it for the rest of her life. She’s still working through it all.”

“She always comes off so strong and bold, and she is. But this is also so crippling,” the source added. “Still, it’s made her a stronger person.”
