If you’ve ever stayed in a relationship because you thought you could “fix” the person you love, then you have a kindred spirit in pop icon Toni Tennille. She looks back on her 40-year marriage to Daryl Dragon, aka The Captain, and explains why love couldn’t keep them together.

She also describes why she decided, at the age of 75, that she’d had enough with the negativity and instead wanted to focus on joy, beauty and positivity for the rest of her life.
