Tia, who competed on Arie Luyendyk Jr.'s season of The Bachelor before looking for love on Bachelor in Paradise's fifth season, took to Instagram on Monday to confirm her split from Cory, who is reportedly the executive vice president of his family's steel company, Cooper Steel.
"It's so wild that I feel the need to share this, but let's rip off the bandaid...No, I am no longer in a relationship," Tia, 28, captioned a photo of herself laughing in a very sexy black dress with cutouts.
"I am fine. He is fine. At this stage of life, we are better as friends. He is a very private person and will freak when he reads this, but I wanted to address it myself."
Tia debuted her romance with Cory in November 2018 when she shared an Instagram photo of herself with a mystery man standing on the sidelines of Nissan Stadium's football field in Nashville, TN.
While Tia's relationship status remained unclear at the time based on her vague "Nashville weekends" caption, comments poured in from her Bachelor Nation friends, confirming the brunette beauty had a new boyfriend.
"Whoaaaaaaah IG offish finally!! happy for you two love birds," wrote Tia's fellow bachelorette Caroline Lunny from Arie season of The Bachelor.
And Raven Gates, who appeared on Season 5 of Bachelor in Paradise in 2018 when Tia was dating Colton Underwood, wrote, "Nashville and love look good on you."
Tia continued in her Instagram post on Monday, "It's tricky being in the public eye."
"Social media is a huge platform that allows me to share this highlight reel of my life with SO many people, but when it comes to private matters, it's not so easy for me to share...especially when another person is involved."
Tia added, "At the same time, I want to be vulnerable and real because it's humbling that all of you take the time to care about what's going on in my life-the good and the bad. Thank you for the continued love and support."

Tia suggested there may be bad blood between Cory and herself or he did something wrong in the conclusion to her post, but she didn't elaborate.
"I'll leave you with this quote from Destiny's Child, 'You know I'm not gon diss you on the Internet, cuz my momma taught me better than that.' Ok bye don't message us," she wrote.
Tia and Cory documented their romance on social media for the past year.
Tia's most recent post about Cory dates back to late August when she apparently enjoyed a "staycation" with him in Nashville and her dog Marlo.
A few days earlier, Cory shared a photo showing that Tia attended a fundraiser with him for the Lwala Community Alliance.
In early August, Cory also publicly wished Tia a happy birthday.
"Happy Birthday to the most amazing, funny, caring person I've ever met. (Did I mention absolutely gorgeous?) Who would have known that a co-worker's love for a reality TV show and a private Instagram message... would lead me to someone as incredible as you?" he wrote at the time.
"I couldn't possibly be more thankful for you, @tiarachel91 hope your day is the BEST!"
Based on social media, Cory appears to be a big family man. His father and grandfather apparently founded Cooper Steel company over 50 years ago in Tennessee.
After Tia failed to find lasting love with Arie onThe Bachelor and then split from Colton on Bachelor in Paradise 5, she was briefly linked to former Big Brother houseguest Corey Brooks in September 2018.
