Maurissa, who first competed on Peter Weber's The Bachelor season in 2020, got engaged to Riley, a New York-based attorney, on Bachelor in Paradise's seventh season in Summer 2021.
Following weeks of breakup speculation, Riley and Maurissa confirmed their split in a joint statement on January 24, only three months after their engagement aired on Bachelor in Paradise's October 2021 finale.
"Everything [Riley and I went through] -- our whole relationship was legit, of course. I loved him from the bottom of my heart, I'm sure he loved me back. But it just didn't work out," Maurissa said on an April episode of "The Ben and Ashley I: Almost Famous podcast" co-hosted by Ben Higgins and Ashley Iaconetti.
Maurissa also shared a video without her engagement ring and a cryptic quote that read, "All that glitters is not gold," which suggested Riley may not have been all that he was cracked up to be.
In late February, The Bachelor alum Demi Burnett appeared to suggest Riley may have been at fault for the split, and Maurissa "liked" the tweet.
"Y'all got the Maurissa and Riley break up SO WRONG," Demi tweeted on February 3, adding, "I'm mad at the BS being portrayed!... I don't want to talk about it bc it's stressful and not my business to tell! BUT LOOK DEEPER LISTEN TO UR INTUITION."
And several weeks later, Maurissa appeared to slam Riley by retweeting two of The Bachelor alum Deandra Kanu's Twitter posts that were also seemingly aimed at Riley.
"I'm not an inherently messy person, but when I see things in real time and then see someone skew that perception for social media it's very scary," Deandra wrote at the time.
"It's not okay by any means to be the catalyst of your own demise and then go onto socials and ask for the publics sympathy," she added in a second tweet. "There are always two sides to a story."
While Deandra didn't name Riley directly, her tweets came only one day after Riley posted a lengthy statement on Instagram about how he was trying to "heal" and bounce back from his breakup with Maurissa.
As far as Maurissa bouncing back goes, she said she's older and wiser now and ready to find her future husband.
"I'm more mature now. I've been here and I know what I want in a man. I think I was unsure going in [to The Bachelor franchise]," Maurissa acknowledged.
Maurissa previously said, however, she's not ruling out men from Bachelor Nation and would "be very open" to appearing on Bachelor in Paradise again.
"There are so many amazing people that come out of Bachelor Nation, okay? I would be up for it, yeah," Maurissa told Ben and Ashley last month, adding how she does believe The Bachelor process works.
But Maurissa advised future Bachelor in Paradise contestants to trust your gut, be true to yourselves, and know what you deserve and really want.
"Make sure you're compatible with how you want to raise kids, how you want to have family, things like that, where you want to live. I made the mistake by trying to sacrifice everything going into it for love," Maurissa shared.
"But I mean, I don't think it was really a sacrifice -- when you're in love, that's what you do... I'm still questioning it myself."
Maurissa, who grew up in a small and rural town, is now back in Atlanta after the breakup.
"I clearly want love, I want marriage. I want babies," Maurissa noted.
As for what she's looking for in an ideal partner, Maurissa disclosed, "I'm looking for someone that knows what they want, and doesn't just say they know what they want."
"They're very ambitious. Someone that wants the same things I want... I know the right questions to ask, you know? I know not to just fall in love with somebody right away that says, 'Oh, you're pretty... and I want to take you on a date.'"
Maurissa confessed falling head over heels for Riley in such a short period of time was "the mistake" she had made, although she doesn't regret any of her Paradise decisions.
"I feel like I was just so ready for love that I would take anything at that point. And now I found myself -- I've done a lot of, like, [self]-help. I've been through therapy, a lot of things like that," Maurissa said in April. "And I just know my worth and myself now."
Back in October 2021, Maurissa told People that she was planning to have a "wedding and then some babies" with Riley.
When Maurissa accepted a pear-shaped diamond engagement ring from Riley on the beach in Mexico in Summer 2021, the pair became the franchise's first-ever Black couple to get engaged.
Riley and Maurissa appeared smitten with each other right off the bat in Paradise, but Riley was still a little unsure as to whether he was going to pop the question following the pair's overnight Fantasy Suite date.
Riley assured People last year that it "was never a thought" to leave the resort alone but he had to take a moment or two to reflect on the idea of potentially making Maurissa his fiancee.
"[I thought to myself], 'This is everything that you've ever wanted -- having a fiancee and being able to start a family.' I knew where I was already leaning towards," Riley explained at the time.
"It's just like, 'This is a big decision, take some time to think about it. Okay, you thought about it.' It didn't take that long. 'And now, go propose and get your lady.'"
Riley proceeded to call himself the "luckiest" man in the world to have Maurissa by his side.
