Jennifer Love Hewitt says it isn't tough going to work, even though she recently split from her Ghost Whisperer costar Jamie Kennedy.

"It's fine," she tells USA Today. "Everyone's a grown-up. It just is what it is."

On Tuesday, the actress, 31, releases her new book -- The Day I Shot Cupid: Hello, My Name Is Jennifer Love Hewitt and I'm a Love-aholic.

Weird timing?

"It's not the ideal situation, but the thing I'm really happy about is that I never say in the book that I know how to find perfect love or how to be in the perfect relationship," she says. "I'm thrust back into the dating world as the book is coming out, so I feel more than ever that people will know I'm kind of with them in the trenches."

She says it isn't tough being single again.

"It's what life handed me, and I'm OK with it," she says. "I know wholeheartedly that I'm a really good partner. I think I'm a really good girlfriend, and I think that I could be a really good wife. I know that I love being able to give my love out to someone. I know there is somebody great out there for me."

Though she's been dubbed a "serial dater," she says she isn't "that different from a large group of people out there who are better and happier when they can spend time with someone."

Despite unsuccessful relationships with everyone from John Mayer to Scottish actor (and former fiance) Ross McCall, she says: "I'm a hopeless romantic. I love love. My middle name is Love. Valentine's Day is my favorite holiday. I want to have a family and children. I am a sucker for every romantic comedy that comes out."

Her tip for getting over a guy?

"You can allow yourself 72 hours of wallowing time," she says. "Then you've got to get into the gym, stop eating the ice cream and move on."
