"Our engagement was exactly how I imagined it. I love you so much Alexandra. I can't wait to spend forever with you lil Al," Garrett captioned a slideshow of photos featuring The Bachelorette Season 14 winner proposing marriage to Alex on the bow of a yacht.
Garrett also added the following hashtags to his post, "#engaged #shellyeah."
Alex also uploaded photos from Garrett's romantic marriage proposal on her own Instagram account.
"When two become one. I love you Garrett Vincent Yrigoyen. I want all of you forever, everyday," Alex wrote alongside the images. "HECK YES I WILL MARRY YOU!!!! #engaged."
Becca made a "last-minute decision" and moved to Los Angeles, CA, in September 2020 to embrace a "new adventure" in her life just about a week after announcing that her engagement to Garrett had ended.
Split rumors began swirling about Becca and Garrett's relationship in June of that year, but neither person spoke on them until Becca confirmed their relationship was over on the September 1, 2020 episode of her "Bachelor Happy Hour" podcast.
"So I don't think it's going to come as a shock to anyone, but Garrett and I have decided to end our engagement," Becca shared with her listeners.
"If you followed us on Instagram for the past couple months, you'll have noticed I spent a lot of time in Minnesota. I was with family and close friends, and he was out on the West Coast doing the same. We were really just trying to take the time and gain some clarity as to what was the next best step in our lives, whether that was together or as individuals."
A source told Us Weekly at the time that Becca "didn't want to be reactive" and "never intended to be cryptic or mysterious" about her relationship status.
And Becca confirmed on her podcast she and Garrett had slowly arrived at the decision to call it quits on their relationship "after many conversations."
"It wasn't something that we just arrived at one night. It wasn't based solely off of one Instagram post or somebody else's opinions or comments. There's much more to it," Becca explained.
Becca was seemingly referring to the thin blue line Garrett had posted in June 2020 on Instagram, which showed solidarity with police forces amid nationwide protests triggered by the killing of George Floyd and appeared to spearhead the couple's demise.
Becca had made it known on the June 9 episode of her "Bachelor Happy Hour" podcast that she did not "align" or "agree with" Garrett's social-media post.
"To any relationship, there's a lot of layers, and it's not for me to divulge details. It's no one's business other than what I'm telling you right now. But for anyone out there who has gone through a breakup, you know it's never easy. It's a roller coaster of emotions," Becca said at the time.
"You have these ups and downs and you try to take it day by day and navigate the best you can, which is why it's taken so long for either of us to say anything."
Becca, however, said in her breakup announcement that she and Garrett had enough time to "come to terms" and be at peace with their choice to split.
"We've realized that we still have so much love and kindness and compassion in our hearts for the other person, but sometimes people's paths just go different ways... Life happens and sometimes people drift apart and have differences," Becca noted.
Becca added that it was "really hard" to talk about her breakup publicly and she needed "time to heal."
E! News first reported in August 2020 that Becca and Garrett had called off their engagement after the pair was noticeably spending a lot of time apart.
"Their lifestyles don't mesh anymore. Garrett wants different things and they came to a realization that they aren't compatible anymore," a source told E! News at the time, adding, "They are trying to keep it low-key because they are still working things out, but the relationship is definitely done."
Becca and Garrett, who had lived in Carlsbad, CA, together prior to their split, got engaged in August 2018 during The Bachelorette's Season 14 finale.
Becca revealed she was ready to tie the knot with Garrett in December 2019 and the pair's relationship seemed to be strong and thriving in May 2020, but then the drama began in June 2020 with Garrett's response to the "Black Lives Matter" movement and Becca seemed uncertain about their future together.
"And I've said to her, 'I will not f-ck with him.' He has doubled down on his beliefs. This isn't the first time he's had problematic behavior," Rachel said.
Garrett came under fire in 2018 as Becca's The Bachelorette season was airing on ABC for his taste in offensive, controversial and politically-extreme Instagram memes involving undocumented immigrants, Parkland shooting survivors and more.
In late May 2018, Garrett issued a public apology, saying he never knew "the power" behind "a mindless double tap on Instagram," referring to how he had liked insensitive content.
During Garrett's first scandal in 2018, Becca wasn't aware of Garrett's social-media behavior while her The Bachelorette season was filming.
She therefore asked fans during an interview with Entertainment Tonightto "stay open-minded" because she couldn't fault anyone for what they believe.
"I am a strong woman and I do believe in certain things, but again, that's what's so great about our country -- everyone is entitled to their own opinions," Becca said at the time in Garrett's defense.
