I agree with LIS. I think that right now it is pursuing. She really needs the time and the space to see what life will be like without you. I know that it has been 5 months since she left, but she just moved into her new place and is still in the 'excitement' phase of her new life. I say continue doing what you are doing. Let her begin to realize that her new life isn't all that great. See if she begins to miss you.
If you write a letter, an idea that I don't like, or decide to have a conversation with her about this issue, it will only come across that you are still waiting for her. This is the opposite of what you want right now.
