On Bachelor in Paradise's Season 7 finale, Becca was shown breaking up with Thomas and crushing his heart before overnight Fantasy Suite dates because, despite having "an incredible start" to a relationship, Becca worried their romance was "too good to be true."
Becca, coming off two broken engagements, didn't want to leave The Bachelor franchise for the third time with a man unless she knew everything about him, including how he'd face adversity in the real world.
Recalling the night of their breakup, Becca told E! News that she returned to her hotel room in Mexico crying.
"I was just sobbing," Becca admitted. "I was like, 'I gotta get his number and reach out to him and see if I can make amends.'"
On Becca's way out of Paradise, a teary-eyed Thomas admitted he was "falling in love" with her and had so much faith in what they had and what their future could be like together, which made Becca question her decision and feel regretful.
Bachelor in Paradise's finale concluded in October 2021 with an update on Becca and Thomas' relationship that revealed the pair had reunited after filming ended and are now dating, "happy and in love."
Becca, who starred on The Bachelorette's fourteenth season in 2018, said when she realized Thomas wanted to fight for her and their relationship, she was prepared to do the same.
"Everything, I would say, happens for a reason," Becca explained to the website.
"When we were dating on the beach for that short amount of time, everything was smooth sailing. It was perfect... But for me, I needed more of the real life. I think to go through that breakup in that very short courtship ultimately brought us back together."
They are currently house hunting together and looking for a "permanent spot for both of us."
As far as their daily lives go, Becca and Thomas shared how they enjoy going to hole-in-the-wall restaurants around town and spending time with their dogs at the park.
Becca and Thomas then typically have a game night and they said they hop into bed by 10PM.
"I would say my favorite quality about Becca is her desire to experience," Thomas said. "She understands that life is the most beautiful thing and she's not afraid to go all in and go for things. It's a fun life."
And Becca suggested Thomas is patient and makes her appreciate the little things.
"He makes me sit back and be like, 'We have a great life, you are so blessed for everything that you've been given,'" Becca gushed.
"Enjoy the little moments. Enjoy the people that you meet, the interactions that you have. He just makes me slow down and enjoy the small moments in life and I think that everyone can do that."
He added, "Am I aware if I have one in a safety lockbox in my bedroom? I don't know, time will tell. We'll have to find that one out later on this year."
Back in early November 2021, Thomas told Hollywood Life that he was pretty sold on marrying Becca because they were spending a lot of time together and had "the most healthy, normal relationship" at the time.
During an October episode of the "Talking It Out with Bachelor Nation" podcast hosted by The Bachelorette alums Mike Johnson and Bryan Abasolo, Becca revealed how Thomas has sent her "multiple text messages" asking about engagement rings.
"It's something we've talked about," Thomas disclosed during the joint interview. "I mean, I don't want to spend my life with anybody else... I wouldn't want to wake up next to anybody else."
Before falling in love with Thomas, Becca had her heart broken by Arie Luyendyk Jr. on The Bachelor's 22nd season in 2018, when he decided to end their engagement because he was still in love with his runner-up, Lauren Burnham, who is now his wife and the mother of his three children.
Becca also had a very public breakup with her The Bachelorette 14 winner, Garrett Yrigoyen, in mid-2020.
But the third time may be the charm, as Becca has been thinking for nearly a year now that she and Thomas are meant to be.
"I'm gonna probably hate myself for actually admitting this to anyone, but I called my mom -- and even though I was engaged twice in the past -- I was like, 'Mom, I think I want to marry this guy,'" Becca previously said on the "Talking It Out" podcast.
"It's the first time I've ever actually said that out loud."
Since the pair began dating in the real world, Becca has defended Thomas and stood up for their relationship on more than one occasion considering he had been portrayed as a villain on Katie Thurston's season of The Bachelorette.
