"Why not? We are madly in love, we love being together, our relationship is easiest when we're together," Harris told TVGuide.com. "It's just the most simple answer: We're so excited to be together."
The two announced during The Bachelorette: After the Final Rose that Harris will move into Swiderski's Chicago apartment in September. They plan to wed within a year.
The couple has overcome some hurdles, including Swiderski's initial inability to, uh, take things to a physical level in the Fantasy Suite. Swiderski said he was "a little stunned" the show would focus on the most personal of personal issues, but he "wasn't too upset because I knew the outcome of the show and I was okay with it."
Ed has also made it through career stress. After leaving the show at one point to focus on his job, Ed says he and Jillian now agree it's time to put love first.
"We're both young, career-driven, entrepreneurial types and I have learned from the past how hard that can be on a relationship...It's all about balance, and he's doing a really great job of that so far," Harris said.
