It is time to become distant. Its time to stop telling her that you love her, its time to really go out and get your own life. What is happening is that you telling her that you love her and know that you will be ok is going to push her away. She is already feeling guilty so you pushing the issue will not help. I would stop calling her unless it is a matter of business. She needs to see that you are okay. She needs to know that you will live without her but would choose to stay with her. It seem counter productive but I know when my wife wanted a D It worked for me.
