In a photo taken Monday, 25-year-old Gordon is seen walking with his mother, Michelle Gordon, while wearing Brown's engagement ring on a chain around his neck. (While Gordon and Brown called each other husband and wife on social media, they never actually married.)
"Nick is very upset," a source told PEOPLE earlier this week of Gordon. "You can say what you want about him and Bobbi Kristina, but he really did love her very much and is devastated that she is gone."
Brown – the daughter of Bobby Brown and the late Whitney Houston – died Sunday at an Atlanta-area hospice facility, nearly six months after she was found unresponsive in her bathtub. She was 22.
Gordon is facing a $40 million civil lawsuit. In the papers filed by Brown's conservators, he is accused of domestic abuse and stealing money.
