— -- Former "Bachelor" star Sean Lowe knows what it's like to be in Andi Dorfman's situation right now.
However, he warned her not to call her new fiancé, Josh Murray, her "soulmate."
"Mainly, I’d tell them not to elevate the other to the level of 'soul mate,'" he wrote in a blog post of the advice he'd give the newly-engaged couple. "It sets everyone up for unrealistic expectations and emphasizes the romance over the hard work of building a relationship."
Lowe, 30, married Catherine Giudici, 28, in January, a little more than a year after they announced that they'd gotten engaged on the season finale of "The Bachelor." Lowe explained that their relationship has "definitely taken work," especially the time after the show and before their televised wedding.
"Falling in love while globetrotting the world was the easy part," he wrote. "Learning how to love someone you’ve spent a collective 20 hours with is the really hard part."
Still, he wished the happy couple nothing but the best.
"Catherine and I are so excited for Andi and Josh," he wrote, "and hope this time without the lights and cameras will bring them ever closer to the time when the minister pronounces them -- not 'soul mates' -- but 'husband' and 'wife.'"
