Exactly what my wife did. She had waist length hair for a few years. She knows how much I love long hair and I always combed and braided it for her. But she felt it was uncomfortable and got her hair cut. So I was sad for a while but I got used to it. Now, after a few years with Bob, she is growing her hair again. Give your wife time, without pressuring her, and maybe she will grow her hair again. it depends on how she feels about herself .
