According to sources, the eighteenth-season The Bachelor pair have split and it was Ferrell's decision, Us Weeklyreported.
Ferrell, 27, unfollowed Galavis, 33, on Twitter and Facebook on Sunday. She also posted an image featuring a cryptic message on Instagram.
"Isn't it pathetic how we waste so much time on certain people and in the end they prove that they weren't even worth a second of it," the message read, adding in her own caption, "Nope not one single second."
In the last day, Galavis has also reportedly followed and unfollowed Ferrell multiple times.
"Sometimes you WIN, sometimes you LOSE... You will ALWAYS learn..." Galavis tweeted on Sunday morning.
Galavis selected Ferrell at the end of his The Bachelor journey but didn't propose or even say, "I love you" to the pediatric nurse -- despite her repeated expression of love -- in the finale episode, which aired in March and taped in Fall 2013.
Following months of reports the couple was on the rocks, Galavis and Ferrell appeared on VH1's Couples Therapy with Dr. Jenn.
"It's not a word; It's a feeling," Ferrell countered in tears. "It's not a word."
"I feel like I cannot be without her... She wants to hear 'I love you,'" Galavis explained during a therapy session. "To me, it kind of sucks that just three words will make her feel 100 percent confident."
Expert Janine Driver, who is known as "a human lie detector," then assisted Dr. Jenn Berman in demanding Galavis respond with a "yes" or "no" type of answer to, "Whatever the language is, do you love Nikki?"

"I can say, 'Yeah, I'm falling for her big time,'" Galavis replied. "But do I love her? As to tell her, 'I love you?' Nah."
Galavis and Ferrell had been trying to make a long-distance relationship work, as Galavis lives in Miami, FL, and Ferrell currently resides in Kansas City.
