She married Daniel Clark in 1994 and divorced him in 1996. They did not have any children. She then dated the actor, producer, Peter Facinelli. Peter was her boyfriend, while she was still married to Daniel. They fell in love on the sets of the film, An Unfinished Affair. Peter married his girlfriend, Garth, after dating her for 5 years. They got married on 20 January 2001. They have three daughters, Luca, Lola, and Fiona. This marriage only lasted for 11 years. They filed for divorce and split in 2013.

It was one of the most amicable break-ups in the Hollywood history. They have not split their money. They want to raise their daughters with shared finances. Their split was based on Garth’s personal discomfort and anxiety about the matrimony. The couple, after their split, still finds each other dependable but not as husband and wife. The differences between them started when Garth opted to nurse her children while staying on the ranch in Arizona. Peter was focusing on his career, producing and acting in films and sitcoms. This distance between them made her feel miserable, and it started to effect their relation. She would miss him and would yearn to see him. It made her very anxious while he was away shooting in various locations.

They could not spend time with each other anymore. After having a successful career, when Garth had to stay with her mother on a ranch and raise her children, it made her uneasy. It gave her mixed feelings about her role as a mother and a partner. Soon she saw how she and Peter grew apart, unable to connect with each other. It is not true in this case that, “distance makes the heart grow fonder.” It is a key factor to that ended this union. Since cheating was not the cause of their split, their spousal relationship ended peacefully. There were no ugly fights over money or custody of children. They knew their differences and wanted the best for their children. They decided to provide full support to their children, together, in spite of their split.
