The Bachelorette star Katie Thruston has accused Greg Grippo of not knowing anything about love on her After The Final Rose special. Prior to this ATFR, Greg left the show upset at Katie for dismissing his feelings following their hometown date. After their blowout fight, Greg walked away, leaving Katie in tears. The next morning, Greg went to Katie's room, where he told her he was eliminating himself from the competition. Greg felt he gave her his all, and she was giving him nothing in return.

While they both left each other heartbroken, Katie was also confused by the entire situation. She believed Greg could possibly be her final pick, especially since he was the one who received her first impression rose. But after he self-eliminated, Katie was left confused about the situation. She still had a great deal of love for him and wanted to see how their relationship would progress over the last few days. However, it seems Greg could no longer be with Katie without a better understanding of where he stood with her.

The finale of Katie Thurston's season of The Bachelorette airs tonight, along with the After The Final Rose airing right after. In an exclusive sneak peek from ABC (via Us Weekly), the 30-year-old confronts her ex. "I’m devastated," Katie tells co-hosts Kaitlyn Bristowe and Tayshia Adams in the sneak peek. Greg then proceeds to tell her, "I emptied my heart out to you," to which Katie fires back, "I don’t think you know what love is." The viewers saw the end of their relationship go down on last week's episode when Greg felt like Katie was dismissing his feelings after he poured his heart out to her. "I am in love with you. You just make me the happiest I’ve ever been. I see it with you. This is real to me," the 28-year-old said after he opened about losing his father. "I haven’t been this vulnerable with anybody in my life."

Katie then replied, "I just love looking at you," which promoted the New Jersey native breakup with Katie and leave the show. Greg told the former banking manager that when he was opening up to her, he "felt like [he] was telling that to a stranger." The love that he had for Katie, he felt was not reciprocated back to him. "I was thinking that I was expressing my love to my future wife, and you didn’t even feel it," he said, adding that while leaving their relationship will hurt, he cannot continue their romance like this. "I’ve reached my breaking point with this [...] I really hope you find something," he said as he exited her room. Katie confirmed on Saturday that they will be discussing her and Greg's relationship and his acting past.

At the After The Final Rose ceremony, Katie and Greg will come face to face for the first time since he exited the show. Katie will express her feelings regarding the breakup and Greg does not plan on holding back either. As for a future reconciliation between the two, that doesn't seem likely at this moment.
