When it comes to finding love, there are certain things Taylor Swift won't compromise.

"I can't deal with someone wanting to take a relationship backward or needing space or cheating on you," she says in the December issue of Cosmopolitan. "It's a conscious thing: it's a common sense thing. ... I just don't ever want to end up in a relationship that isn't fair ever again."

Although she's been linked to actors, musicians and even a Kennedy, Swift, 22, is more concerned with chemistry than anything else.

"I need that unexplainable spark," she says. "I just need to see someone and feel oh, no, uh-oh. It's only happened a few times in my life, but I feel like if I was gonna be with someone forever, it would be because I saw them and I thought, Oh, no."

But while her love life provides endless inspiration for her hit songs, the Grammy Award winner says there's only one thing she'd do if she wasn't making music.

"Being a mom full time, doing everything for my kids, having a bunch of them," she says of her future aspirations. "That's the only other thing that could be as thrilling for me as doing this."
