Earlier this year she posted pictures of a tattoo she got in his honor, and Wednesday -- on the anniversary of his death -- she shared emotional words about the "Glee" star on Twitter.
She honored his life in the most beautiful way. It's a picture of Cory on a beach with the words,
"I know everyday you're watching over me, and smiling. Love and miss you Cory, everyday, but today a little more."
Her heart-wrenching tribute has been shared nearly 50,000 times.
Thousands of people including his former co-stars were honoring his life with the hashtag #3YearsWithoutCory on Wednesday.
Actors were sharing special moments from their time with Cory.
In April, Lea got a number 5 tattoo, which was Finn Hudson's football jersey number on “Glee.”
She posted a picture on Instagram and wrote, "For my quarterback."
The couple dated for almost two years until Cory's death in 2013. He died of a drug overdose.
