What has changed about you that she doesn't like anymore? Is it something physical or in the way that you act towards her? It sounds like during your illness you two really disconnected emotionally. 5 years was a long time for her to wait for you. She probably disconnected to protect her feelings for you and the stop the hurt from missing you and now finds it hard for them to return. You may have even built a wall to protect your feelings while you where ill.
It is almost like starting over and may take a long time to rebuild what you once had together. As I have found, it won't happen overnight. The changes have to come slow and the trust has to build again. I can't tell you how many times I have had to experience that backslide. You think things are fine and then it feels like you are back at square one again.
