Well in Halo Combat Evolved, Chief took Cortana to keep her safe from the Covenant. In Halo 2, Chief took her to disable the bomb, and kept her in his head until she had to stay behind on High Charity. Then, in Halo 3, he had to go back for her because she had the Index to Instillation 04. Then they were together on the Dawn, hence they are still together.
