I know the emptiness you speak up. Its an unbearable void. But you can do something about that. YOU can fill that void. And you should fill it. We can't rely on other people in life to make us feel whole and complete. We have to be "enough" for ourselves first. That's hard. Its easier to let other people make us feel good about ourselves but no one else can ever make us complete. We have to do that ourselves. Start today. Your weekends are wide open. Find something to fill them up. Look on MeetUp dot com. Are there groups in your area that would interest you? I see that you are going to work on finishing your degree. Awesome. Are there any groups associated with the college that you could join? You can't "shake" her up. You've got to spend this time working on yourself. She is seeing the changes in you. Keep them coming. But do them for you, not for her.
