Jennifer Aniston and Justin Theroux seemed ready to tie the knot – but now there’s no date in sight. Sources in this week’s issue of PEOPLE reveal why she’s fine with waiting – for now. In the 10 months since their August 2012 engagement, all eyes have been on Aniston, 44, with fans wondering just when she will become Mrs. Theroux. But multiple sources in contact with Aniston and her inner circle (who spoke with PEOPLE anonymously to protect their relationship with the actress) say that plans for the much-anticipated wedding, under way earlier this year, appear to have stalled.

As of a few months ago, “wedding bands were designed, and Jen was deciding on a dress,” says an insider who speaks to Aniston often. “She was happy to be planning.” Aniston had picked a date, too, for a spring affair, this source claims. A second source, who frequently works with Aniston, confirms that earlier this year, “her team was trying to clear her schedule for a spring wedding.” Now, as weeks pass, Aniston and Theroux, overloaded with work commitments and a time-consuming home renovation, have put arrangements for their big day on the back burner. At the moment, “there is no new wedding date.”

So why haven’t they sealed the deal yet? One reason could be that their careers and their massive home overhaul have taken priority. In January 2012 Aniston bought a $21 million, 8,500-sq.-ft. Bel Air estate she hoped to transform into the couple’s dream abode. Eighteen months later the home has a 2,000-sq.-ft. addition, a new guest house, a pool area with black lava veneers and a pizza oven. But it’s still not finished. “With all the work on the house, they just thought it was too much to plan a wedding as well,” says the insider. “So they decided to step back and just focus on the house.” (Some sources have hinted that it could be a wedding venue.) Aniston and Theroux, 41, who have been holing up at a nearby hotel, have spent a few nights there. “They can’t wait to move in [fully],” says the insider. “They’re eager to get the house all ready.”

A source who knows the couple professionally cautions that the lack of a wedding date isn’t an indication that anything is amiss. “Jen has a very happy life and doesn’t want that to change,” says the source. “There are other priorities [besides marriage]. She’s very busy.” But the insider says that Aniston is ready to say “I do” whenever the timing is right: “Jen is crazy about Justin. And she can’t wait to be his wife.”
