(CNN) -

Charlize Theron's recent adoption of son Jackson may have seemed out of the blue, but becoming a mom was always on the 36-year-old star's agenda.

"Motherhood was something I always knew I wanted to experience," Theron told InStyle in its June issue, adding that adoption has been a "great opportunity for someone like me who wants to have a family. ... I can only hope to be 10 percent of the mom mine was to me."

Theron added that her mom encouraged her "to be confident and enjoy life," and that's what she wants to share with Jackson. "So far, I'm not surprised by anything about being a mom," she said. "It's all pretty great--but that's what I expected."

And it looks like Theron's content to raise little Jackson solo, at least for now.

While she told InStyle she is "open to a relationship," she added, "I'm not putting those feelers out there now."

It's not that she's down on relationships - "I am a relationship girl ... That's kind of just how I'm made," Theron clarified - it's just that the actress doesn't see a partner as an absolute necessity.

"Maybe I'm just really lucky that I was raised by parents who just - I've never gone through my life feeling like I was only half a person until I met someone else," Theron told Celebuzz.

"I feel that my relationships have been such blessings because I've been allowed into someone's life," she went on. "They of course make you better and all that stuff, but I never thought of myself [as] less of a person once I left a relationship."
