I can understand you not wanting to bring her home, and it may not be good for her anyway...for instance, if you made changes how would she react to the notion of you seeming to move on? I suspect she needs somehow to start viewing where she is as home now, and going back will not help her. Are there other places you can take her to visit? A nice park perhaps, or a cosy cafe...somewhere you can go regularly together and make your new special 'together place'? Also, do you have children you can vusit together?
