Ridge slept with a drunk Caroline and, after fighting with his brother, Thorne divorced Caroline.
He took an interest in Macy Alexander (Bobbie Eakes), and the two fell in love.
Their relationship was not received well, since Macy and Thorne worked for opposing fashion enterprises.
They married and divorced shortly after, and Thorne started dating Karen Spencer (Joanna Johnson).
Ivana was jealous of their relationship and sent Macy threatening letters.
Thorne then fell in love with another of Ridge’s exes; this time, it was Taylor.
Taylor refused and revealed the paternity results to Ridge, and they reunited.
After their wedding, Macy was presumed dead in a car crash and Thorne went back to Brooke.
He entertained a relationship with Macy’s half-sister Kimberly (Ashley Lyn Cafagna) but married Brooke instead.
Macy was killed by a falling chandelier and Thorne was left to move on.
Darla had their daughter Aly (Ashlyn Pearce) but was killed in a car accident.
However, they annulled their marriage as they grew apart.
