'Bachelor in Paradise' stars Kylee and Aven have split, just days after the season finale

• Spoilers ahead for the finale of "Bachelor in Paradise" season nine.
• Kylee Russell and Aven Jones connected early on during this season of "Bachelor in Paradise."

Kylee Russell and Aven Jones had an instant connection on this season of "Bachelor in Paradise," and they didn't care who knew it.

Kylee emphasized in her introduction that she was really excited to meet Aven, who she said repeatedly liked her Instagram photos and once even sent her a fire emoji in response to one particularly enticing picture.

And after they went on their first date during the first week of "Paradise," Kylee and Aven were basically inseparable.

The two seemed on track for an engagement. But during the "Bachelor in Paradise" finale, which aired Thursday, Aven was adamant that he wanted to continue dating off the show. Despite some pushback from Kylee, who was clearly gunning for an on-air engagement, the two ultimately left the show as a couple, but before a proposal could take place.

The "Where are they now?" montage at the finale's end revealed that Kylee and Aven were still dating after the show wrapped. However, just a few days after the episode aired, Kylee revealed the two had separated after "multiple infidelities."

Aven apologized to Kylee after she went public with their breakup

"I want to first and foremost apologize to Kylee, my family and my friends for my actions. I have made major mistakes in the relationship and hurt someone who was very close to me," Aven wrote in a statement posted to Instagram stories.

He continued: "At this time, I am in an extremely low place trying to work on myself. I am doing my best to find healing, find myself and be a better person. Please have grace and respect for Kylee and her family during this difficult time."

Aven didn't share any other details about his split with Kylee at the time.

On Saturday, Kylee wrote on Instagram that their relationship had 'dissolved'

In a statement posted to her Instagram story, just days after the season wrapped, Kylee announced the end of her and Aven's love story.

"Following our relationship announcement yesterday, I want to thank my God he did not allow me to live another day in the dark," Kylee wrote. "In the last 24 hours I have been grasping with the fact that one of the most important relationships in my life has dissolved due to multiple infidelities."

"This is not just a show but my real life and for the foreseeable future, I will be in a time of healing and trying to put the puzzle pieces of my life back together," her post continued.

When she posted the announcement, all photos of her and Aven, including their relationship announcement on Friday, had been deleted from her Instagram account.

Kylee and Aven were on track to become a 'Bachelor in Paradise' success story

Based on a monthlong gap in posts on both Kylee and Aven's Instagram profiles (like all good influencers, they dutifully post at least once every three-ish weeks), it seems as though "Paradise" was filmed in June of this year. Reality Steve also said the show filmed for about two-and-a-half weeks, starting early June.

Until their breakup, Aven and Kylee had liked every post from the other person without fail. Kylee had also posted several photos (now deleted) with Aven to her Instagram page.

While Aven appears to be still following Kylee on Instagram as of Monday, Kylee does not follow him back.
