After 15 years of marriage, Damon chose to divorce Lisa because he was unhappy with their relationship, and they went their separate ways.
In 1999, he began the divorce process with Lisa, and it was concluded in May of the following year. Damon moved on after the divorce and began dating Charity Duplechan in 2003; they are still together now.
Lisa, on the other hand, is still single, in large part due to the fact that she is a mother.
