"What happens on the Internet or on TV, or the speculations that people make does not define the outcome of our life," Harris told People.
"You don't really fall in love until three to six months after the show ends. Luckily with Ed, we are a lot alike, we have the same values, we have the same upbringing. I really fell in love with him after the show."
Harris and Swiderski originally planned to announce their wedding date during The Bachelor: On the Wings of Love premiere in early January, but subsequently changed their mind because they were "worried about how the announcement would have affected their personal life," according to ABC.
The couple still hasn't gone public with a date.
"We are definitely in love and we definitely are going to be married," she told People. "We're hoping it will be in the next year or two. We're both excited."
The couple recently moved into a new Chicago townhouse together.
