STAMFORD, Conn. (AP) A woman has pleaded guilty to setting fire to a Stamford home that belonged to her ex-boyfriend's mother.

Authorities say 34-year-old Felicia Langley of Norwalk set the fire days after discovering that her ex-boyfriend had married her cousin.

The Advocate of Stamford reports that Langley pleaded guilty Wednesday to third-degree arson. She also pleaded guilty to a third-degree burglary charge for breaking into her old boyfriend's apartment and stealing the dress her cousin was married in.

The fire set in August 2012 caused more than $100,000 in damage.

Langley told detectives that she could not eat after learning of her ex-boyfriend's marriage and became even angrier when the couple would not return her calls and her cousin changed her telephone number.

She faces a year in prison.
