Taylor Swift has sung about her relationship ups and downs but there are a few things the singer says she won't put up with.

"I can't deal with someone wanting to take a relationship backward or needing space or cheating on you," Swift said 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."

The 22-year-old singer, who recently split from 18-year-old Conor Kennedy, told the women's magazine that she is looking for a spark in her relationships.

"I need that unexplainable spark," Swift said. "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."

Swift's fourth album, "Red," sold 1.2 million copies in its first week. And though the six-time Grammy winner was recently named at the top of Forbes' list of Highest Paid Stars Under 30 after earning $57 million between May 2011 and May 2012, there is one thing that would make her quit.

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