Since thecollege admissions scandal broke,Lori Loughlin’s every move has been under scrutiny. But while some have criticized theFuller Housestarfor seeming indignant in the wake of the scandal, a legal source says that’s far from the truth.

“Lori is remorseful, and she has definite regrets,” the source tells PEOPLE about Loughlin, 56.

“She’s embarrassed and hurt, and she knows that her reputation has been ruined for life. But she also believes the allegations against her aren’t true,” the source shares.

“She honestly didn’t think what she was doing was any different than donating money for a library or athletic field,” adds the source. “That’s the crux of why she pleaded not guilty.”

On March 12, the U.S. attorney’s office in Massachusetts announced it had indicted Loughlin and her husband Mossimo Giannulli, 56, in the shocking nationwide scam dubbed Operation Varsity Blues. The pair and nearly50 other parents, coaches, exam proctors and admissions counselors are accused of such actions as paying for boosted SAT scores and lying about students’ athletic skills in order to gain them acceptance to elite colleges including Yale, Georgetown and Stanford.

Loughlin and Giannulli allegedly paid $500,000 to admissions consultant William “Rick” Singer to falsely designate daughters Olivia Jade Giannulli, 19, and Isabella Rose Giannulli, 20, as recruits to the University of Southern California crew team, though neither actuallyparticipated in the sport.

While 14 defendants, including actress Felicity Huffman, agreed to plead guilty in April, Loughlin and Giannullideclined a plea deal.

“They weren’t ready to accept that,” says the legal source.

Still, the waiting can be excruciating.

“Lori is ready for this to be over,” says the source. “They all are. At this point, it would be better to spend a few months in jail — because she’s been spending the last several months in her own prison.”
