"I don't like to go out to clubs and party. I'm not into 'Let's go out with one guy on a Monday and another guy on a Wednesday' – that's just not me," Hewitt, 31, tells PEOPLE. "I'm a relationship kind of girl. I like a twosome. Some people get excited about being single. I don't."
Hewitt and her Ghost Whisperer costar Jamie Kennedy, 39, quietly split recently after a year together.
It was "a mutual decision, and we've parted as friends," says Hewitt. "There's no anger, there's no upset, there's no enemies." Hewitt adds that the pair's pre-existing friendship has made it easy to transition to working together as exes: "It's been totally fine. It's really a testament to who he is and to who I am. We're both grown-ups."
New BookIronically, the split comes just as The Day I Shot Cupid, Hewitt's new book offering advice and wisdom on dating and relationship hits bookstores. Subtitled Hello, My Name is Jennifer Love Hewitt and I'm a Love-aholic, the book, out March 23, includes Hewitt's own dating horror stories, admissions about her fantasy engagement rings (she's been visiting the same store since age 12 to try them on) and advice on everything from getting over breakups to dieting and cellulite.

Hewitt says she has "no idea" when she'll be ready to date again, though she plans to re-read her own book for advice (and is already at work penning a follow-up).
Independent Working Woman"Back in the shark tank!" she jokes. "I never said in the book that I knew how to be in the perfect relationship. I say in my book I want to be the readers' kind spirit out in the dating world. And now, more than ever, I am."
So for now is Hewitt content to be an independent working woman, or does the self-described "hopeless romantic" still yearn to find true love?
"Both," she says. "I want to be an independent woman who falls in love, finds a great partner for her lifetime, has kids and kind of does it all. I'd like to have it all."
