During an October episode of the "Talking It Out" 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."
On the Bachelor in Paradise 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 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 and real-life challenges.
However, the finale concluded with an update on Becca and Thomas' relationship, revealing they had reunited after filming ended and are now dating, "happy and in love."
During Becca and Thomas' appearance on "Talking It Out," Becca revealed she's the one who tracked down Thomas' phone number and initiated their reunion.
"After we ended things, I think I waited a couple days. I didn't have my phone right away and he didn't have his phone right away, so I think I gave it two days," Becca said.
Thomas recalled, "I was waiting for my bags in the San Diego airport when I got a text."
While Thomas confessed he was "mad" and "hurt" about his Paradise breakup, he had faith they'd have "a future conversation."
"I was just waiting for the moment and opportunity to see her again," Thomas shared.
"When she first texted me, she started off, 'I know I'm probably the last person you want to hear from right now.' And it couldn't be further from the truth, that's the one text I was waiting to hear."
Thomas shared, "That's the one person I wanted to see. That's the one person I wanted to hold... [Our split] showed us that we experienced something and it was taken away from us for a moment."
Becca said she met up with Thomas in San Diego and they picked up right where they had left off, and Thomas told Hollywood Life that he had no hesitation or reservations about giving Becca another chance.
Becca also boasted about how Thomas is different from her past relationships because he's so passionate about a life with her and was prepared to fight "tooth and nail" to save their romance.
"He is so supportive and he's just funny and quirky in the cutest ways. Everything about him, I just felt safe with, unlike anything I had in the past. I was just like, 'This guy is my guy,'" Becca gushed.
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.
"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 said on the "Talking It Out" podcast.
"It's the first time I've ever actually said that out loud."
