Absolutely. IMO, her spiritualism helped her through her grief. And also showed her how much simpler her life could be ( not being bothered w/balls and parties and court life). After the GD assassination, MP asserted that her room became as a nun's cell. Devoid of anyting except bare necessities, painted completely white w/icons and a cross that held the clothes the GD was wearing when he died. Clearly her personality drastically changed after his death. Which leads me back to believe, that IMO she was wholly devoted to him and her marriage wasn't a sham. Just as I believe he was devoted to her. All marriages have problems, but Ella deferred to Sergei in every decision. It must be noted however that he spoiled his wife beyond measure.
