The 41-year-old actress, who separated from her husband Peter Facinelli last year, is currently dating Michael Shimbo, reported E! online.
"It is fun, and it is awful all at the same time. It is like a weird type of torture. But it can be fun. It is super challenging... I expected to come out of divorce and just be great at it (dating)," Garth said.
"I am smart and I thought I could do it. How hard could it be? But I've realised that I have to fumble my way and create the space to really be open to learning because I don't know how to do it," she added.
