She drove him to hospital where doctors found three tumours in his brain - two of which were considered inoperable. He was started on chemotherapy, and had surgery to remove the third tumour, but a month later he died.
He spent that time writing letters to his family. The couple have a son together, Anakin, 12, also Lincoln, Rich’s son, and Lisa’s two kids, Chavez and Brody, from previous relationships.
‘Rich's last words were full of love. His advice to his children was just to make the most of their lives, be happy and have a positive impact on the lives of others,’ Lisa says.
‘What would you write if you knew you were dying? What must have been going through his mind knowing those would be the last he wrote?
‘I will remember him as someone who was always there with a smile and a cuddle.’
Lisa has shared a full letter that Richard wrote just before he died, aged only 39.
