Jane was a shy teenager with a strong faith in God. This faith was ingrained in her by her mother. She believed that good can come out of any adversity. When she met Hawking after his discharge from the hospital, he was in a sad state. She felt that he had lost his will to live and he was very confused. She was not put off by his physical or mental condition. Hawking liked her optimism and their friendship grew. They thought that together they could make something good.
For Stephen, it made a big difference. He applied for a research fellowship at Caius, one of the colleges of Cambridge University. In 1965, when he was 23, he received his fellowship at Caius. In July 1965, he married Jane. They had 3 children. In fact, it was Jane who gave moral support to Hawking to overcome his adversities and do something great for mankind.
