Helen Marshall and Graham Richardson met in school and fell in love.

Teenagers caught the initial sensations, and after nine months of dating, Graham proposed to his fiancée, according to Metro.co.uk.

The man worked on weekends to save enough for a diamond ring. It was so expensive that Graham’s closest buddy thought he was insane after learning about his intentions.

Helen accepted the proposal, but their parents did not approve of their wish to marry since they were too young.

Graham departed for college a year later.

The couple made an effort to communicate, but their parents intercepted their letters. Graham phoned, but Helen was either not at home or was too busy to answer the phone.

The romance was soon over. Helen married, and Graham married. Both had children with their partners: Helen had four children and Graham had two.

The ex-couple barely met briefly at school gatherings and never approached each other.

“I drove slower when I passed Helen to watch her hair flutter in the wind,” Graham remembers. “But I couldn’t talk to her, and it was very upsetting.”

Helen abruptly wrote to Graham on social media 20 years after their high school romance when she discovered that her ex-lover’s marriage had also failed.

Feelings awoke with newfound force, and Graham completed what he had begun in high school by marrying his lover.

During a shared trip to Croatia, he made the second proposal.
