"Right now we just moved in [to] our apartment. We're just starting to furnish it," Girardi toldUs Weekly on Tuesday night. "We will eventually get engaged, yes... We're just step by step right now."
Girardi, who was previously engaged to former The Bachelor: On the Wings of Love star Jake Pavelka, said she couldn't be happier living with Kahl and believes their relationship is nearly perfect.
"I love living with this man because the only thing we ever fought about when we weren't together was that we weren't together," Girardi explained.
"We have an amazing relationship. We really are so happy together! I love going to bed with him and I love waking up to him."
Although the 25-year-old reality TV star only has a promise ring on her finger which Kahl presented her during Monday night's episode ofBachelor Pad's second season to show their level of commitment to each other, the couple is apparently inseparable.
"We actually do everything together," she told Us.
"One of my favorite things to do together is just sit at home and relax," Kahl, 27, added. "I love when she cooks for me because she is an amazing cook."
When Kahl offered Girardi the promise ring, he was surprised by her hesitant "I don't want it to be an engagement ring" reaction.
However, Girardi insisted her hasty response wasn't because she doesn't want to marry Kahl but because she didn't want her engagement to play out on TV again after Pavelka had proposed to her during The Bachelor: On the Wings of Love's season finale.
"For me, I don't want a TV engagement again. I want that to be our engagement, ours alone," Girardi toldAccess Hollywood Live during a Tuesday appearance on the radio show.
In addition, Kahl said the happy couple wouldn't eliminate the possibility of having their own reality show if given the chance.
"If we have a reality show, it would be a big hit -- that's for sure," Kahl told Us.
"We've never thought about it. We're not going to sit here and lie to you and say if the opportunity is presented we're going to say no. If the opportunity is presented, we'll check it out together."
