This doesn't come as a huge surprise considering Nick, 36, and Vanessa, 29 — who announced their engagement in March — revealed that they are in no rush to get married.
Before the finale of the show even aired, an insider exclusively told In Touch that Vanessa was having some serious regrets about her relationship — especially after seeing his behavior on the show.
“Not only was she hurt by what she [saw], but she was so embarrassed by his behavior,” the insider said. “Nick is already very sweet and loving toward her in private, but [she saw] how much of a playboy he is, thanks to the show.”
The couple moved to Hollywood and sources revealed to Life & Style that Vanessa is jealous of fiancé Nick's newfound fame.
Former teacher Vanessa, who’s trying to get acting work, “absolutely hates that Nick is getting more attention than her,” a source said. “She has a manager and an agent, but her acting career hasn’t gotten off the ground.”
Before being cast on the reality dating competition, Vanessa was an aspiring actress, making her acting debut on an episode of Blue Mountain State.
Along with her cameo, the Canadian beauty went on to appear in Being Human and Ascension before turning to teaching.
Meanwhile, Nick has made it clear he is not planning on returning to his old job as an account executive for Salesforce.
"Well, I've been able to do some other stuff as a result of being on so many times," he told Jimmy Kimmel. "I don't do the software thing anymore. I'm lucky enough to have my own."
As for Nick and Vanessa's engagement, it's not looking good.
"Vanessa has told Nick repeatedly,” the source explained, “that if he doesn’t help her get more deals, she’ll tell the public their relationship is fake.”
