And according to a source close to Vanessa, the romance was doomed from the beginning, Entertainment Tonightreported.
"Vanessa is extremely close to her family in Montreal [Canada] and is very connected to her community and her work there," the source told ET of the Italian special education teacher.
"Moving to Los Angeles or elsewhere long term was never really on the table for her. And, unfortunately, it seems as though Nick never had any intention of moving to Montreal."
Shortly after The Bachelor wrapped, Vanessa supported Nick in Los Angeles during his stint on Season 24 of Dancing with the Stars. And in recent months, the pair has been spending most of their time together in California, attending red carpet events and such.
"Vanessa's not really into the whole fame thing," the source explained, adding that Vanessa will probably move back to Montreal in no time. "She's had some fun with it, but that's not what she's about. Ultimately, they want different things."
An insider close to the couple told ET, "Vanessa is an extremely down-to-earth girl and truly wanted that happily-ever-after with Nick."
"They both put in a lot of work in the relationship and care a lot for each other," the insider continued. "However, time proved that they were better off parting ways in the end. It wasn't the distance or the limelight [that broke them up]. They just weren't the best match for each other."
A source told Us Weekly in late June that the pair was fighting often, which didn't come as a big surprise to The Bachelor fans considering both individuals are strong-willed, feisty and stubborn.
Nick even admitted on The Bachelor that the combination of their personalities could be a match made in heaven or a total disaster because they'd butt heads frequently.
It was "very much a real relationship," a third source close to Nick explained, "and there wasn't a straw that broke the camel's back."
"Nick wants to find someone to be with and so does Vanessa. They tried moving in together and supporting each other at different events, ultimately they just weren't compatible," the source said. "They're still friends and keeping in touch. The split is very amicable."
Nick and Vanessa were very open and honest with fans from the start that their relationship wasn't perfect and they had a lot of things to learn about each other and work through. The couple also wanted nothing to do with wedding planning.
"Nick's friends in Bachelor Nation aren't surprised by the split," a fourth source told ET.
"Nick and Vanessa wouldn't really hang out much with everyone as a couple. It was usually Nick alone outside of events. People didn't feel like they knew Vanessa very well. It seemed like from the start, he just did Bachelor to get on Dancing with the Stars."
A few women who competed for Nick's heart on The Bachelor against Vanessa knew very little about their post-show relationship.
"I think [Taylor Nolan] talks to Vanessa, I think [Danielle Maltby] does. I've seen Vanessa here and there. There's no hard feelings, you know?" Jasmine Goode said earlier this week. "I just say 'hey' when I see her. Keep it movin'. We're not, like, besties."
Jasmine said at the time she thought Nick was "sometimes" acting onThe Bachelor and "playing it up" for cameras. Jasmine also called Vanessa "a very emotional person."
Danielle Lombard similarly explained earlier this week, "Vanessa and I don't have a great relationship and I think after things happened with Nick, we just parted ways. In terms of whether or not I think their relationship will last, I don't know."
Danielle L. added that Nick and Vanessa's relationship seemed "very different" from past Bachelor Nation couples because they acted "a little bit more serious." Compared to Rachel Lindsay and Bryan Abasolo, or Kaitlyn Bristowe and Shawn Booth, Danielle L. admitted Nick and his former fiancee's dynamic was "a lot less playful."
