After he was arrested, police found messages showing his "long-standing obsession" with Stephanie, it was said.
He had text his colleague telling her "I want u", and also wrote: "It hurts to see you every day knowing you’ll never like me."
The killer also told Stephanie he would wait "50 years" for her, the court heard.
During his evidence, Rodrigues was asked about a number of "flattering" photos of Stephanie that were found in his bedroom.
He also offered to change his lifestyle and get plastic surgery if it would make him more "attractive" to Stephanie.
How you can get help
Women's Aid has this advice for victims and their families:
Always keep your phone nearby. Get in touch with charities for help, including the Women’s Aid live chat helpline and services such as SupportLine. If you are in danger, call 999. Familiarise yourself with the Silent Solution, reporting abuse without speaking down the phone, instead dialing “55”. Always keep some money on you, including change for a pay phone or bus fare. If you suspect your partner is about to attack you, try to go to a lower-risk area of the house – for example, where there is a way out and access to a telephone. Avoid the kitchen and garage, where there are likely to be knives or other weapons. Avoid rooms where you might become trapped, such as the bathroom, or where you might be shut into a cupboard or other small space.
If you are a -victim of domestic abuse, SupportLine is open Tuesday, Wednesday and Thursday from 6pm to 8pm on 01708 765200. The charity’s email support -service is open weekdays and weekends during the crisis – messageinfo@supportline.org.uk.

And he messaged her asking if her boyfriend had a "bigger one" than him.
But Rodrigues denied being controlling and instead claimed he was concerned for his flatmate's wellbeing.
Detective Chief Inspector Neil John from the Met’s Specialist Crime Command led the investigation and said: “For years Stephanie Hansen tried to extricate herself from Sheldon Rodrigues’ attention, attempting to make him understand that there was no chance of their friendship developing any further.
"Rodrigues refused to accept this and embarked on a campaign of persistent harassment over this time, a campaign that became more intense and sinister as it reached its violent conclusion.
