After a turbulent season of secret girlfriends
, dramatic goodbyes
and suitors around "for the wrong reasons," The Bachelorette
's Desiree Hartsock is happily engaged
– and moving in with her man, Chris Siegfried.
"I truly believe things happen for a reason," she tells PEOPLE. "I have no regrets."
After revealing their love on national TV, Hartsock is ready to move to Seattle – this weekend! – to be with her fiancé. And a wedding is already in the works.
"We're starting fresh," Hartsock says of the new home she picked out for them to move into together.
"I've moved a few things to the place and I've also brought a few things of hers up," Siegfried says. "But we're going to get things together and piece the place together."
Though Hartsock says she would "marry him tomorrow," there is still a lot to consider when it comes to planning a wedding – "possibly" in June, they say.
Like designing her own dress, for example? "Yes, definitely," Hartsock, a bridal designer, says. "Twenties-inspired, a sheath dress with beading or lace."
And will the guest list include a camera crew? "We do want to keep it family and close friends," Siegfried says.
Adds the former
Bachelorette: "And all of America!"
