In pictures: What 50 years of true love looks like.

These photos of couples married for more than 40 years capture the beauty of life long love.

Photographer Tracey Buyce’s mum died in 2007, less than four years later she lost her father. They had been married for 46 years.

The couple lost their 2-year-old son early in their married life and Buyce’s mother turned to alcohol to deal with the grief, but her husband stood by her.

“The happy times are easy, it’s persevering through the challenging times that creates longevity and growth in a marriage.”
