Adam Parker's boyfriend Dean Eastmond died from cancer at the age of 21 in September 2017. They'd been dating for two years.
The couple first spoke on Twitter when Adam sent a message to Dean to tell him how cute a photo of his cat was.
And since Dean's death, Adam has used his boyfriend's tweets to remember him.
"Grief is complex, strange and it works in different ways," the 25-year-old tells Radio 1 Newsbeat.
