"I fell for him hard, and when you fall in love that hard, your heart breaks even harder," Vanessa told People of the breakup in early September.
"In the end, as much as we loved each other and tried to make it work, we just realized we were different people fighting to keep a relationship when ultimately we just weren't the best fit for each other."
Nick and Vanessa both have very similar stubborn and opinionated personalities. When The Bachelor was airing, fans even saw Nick expressing how their dynamic could either be a match made in heaven or a total disaster.
Shortly after The Bachelor wrapped, however, Vanessa supported Nick during his stint on Season 24 of Dancing with the Stars.
In the months leading up to their split, the pair spent most of their time in Los Angeles, attending red carpet events and such, and Vanessa launched a "No Better You" charity while in the United States to raise funds for special education classrooms.
"When you fall in love with someone with all that you have, it's hard to let go. Every part of you gets shattered," Vanessa confessed to People.
