A 38-year-old Louisville woman is facing charges after telling police she got pregnant by a boy who was 13, then continued to have a relationship with him for three more years.

Irene Marie Gomez was arrested last week for investigation of sexual assault on a child and sexual assault.

The arrest stemmed from a reported domestic violence incident between the boy, who is now 18, and Gomez.

According to an arrest affidavit filed in Boulder County District Court:

Louisville officers were called to the woman's home, in the 600 block of Fireside Street, on Nov. 11 to investigate a physical altercation.

Although Gomez initially denied that the fight was anything but verbal, she later contacted police to say she had lied. Gomez alleged that the young man had grabbed her and bruised her arms.

In the course of filing the report, the officer asked Gomez some personal information. She told the investigator she and youth had two children together, one who is now 4 and another who is a year old.

Looking at the birthdates Gomez gave him, the officer realized that the father would have been 13 and 16 when the children were conceived. Gomez was 32 when the first child was born.

Gomez, now 38, said that she had an on-again, off-again relationship with the youth, who stayed with her for weeks at a time after running away from home.

She told the investigators she was unaware he was so young when she first had sex with him because he told her he was 18.

"If you looked at him now, you'd think he was 25 years old," she said.

But the affiadvit also alleges that Gomez acknowleged she continued the relationship after learning his true age a short while later.

"We've been together, we're a family," she said.

She said the two quarreled at times, sometimes over child support, and that the youth had threatened to take her to court for "molesting" him.

According to the affidavit, she told the teen that he was "already over it," pointing out that he had his younger brother come stay with her as well.

"If it bothered you so much, then why did your grandparents and his social worker let your little brother come live in my house if I was such a bad person? And if I was such a bad person, I wouldn't have my kids," she said she told the youth.

When confronted by police, the boy admitted he had been intimately involved with Gomez since he was 13 but he denied being the father of her kids.

He alleged the recent argument occurred because Gomez wrote a forged check for $200 from his account.

When questioned again later, the youth told police he was, in fact, the children's father but did not want to pay support.

"When I inquired further about their relationship," the officer wrote in his affidavit, the young man said, "'I really don't want to go there with you, sir.'"

The affidavit indicates that investigators took DNA samples, but it is unclear whether the results have come back yet.
