She was doing fine until she met Michael Grimm.

The feds are willing to give the disgraced​ ​​politico’s former flame a light sentence for illegal campaign fundraising​ — saying she’d led a respectable life before getting entangled with the former ​Staten Island congressman.

Diana Durand, of Houston, pleaded guilty last September to paying straw donors to cough up $10,000 in illicit campaign cash for Grimm’s 2010 campaign and faces up to a year in jail.

But prosecutors will not oppose her request for probation and a $31,800 fine, according to a Brooklyn federal court filing.

While Grimm was never charged in relation to Durand’s scheme, the letter makes it clear that the feds ultimately blame him for her descent into love​-​struck illegality.

“Notably, it appears that the defendant did not solicit campaign contributions prior to her commission of the subject offense and that the motivating factor to commit the offense related to the defendant’s personal relationship with one of the candidates,” federal prosecutor Marisa Seifan wrote. “The defendant has led an otherwise law abiding life.”

“Accordingly, the government does not oppose the defendant’s requests for a probationary sentence or a fine of no more than $31,800,” Seifan concluded.

After an intensive federal investigation, Grimm eventually pleaded guilty to a tax evasion rap related to his former ownership of an Upper East Side restaurant.

The hotheaded former lawmaker ​– who once threatened to hurl a reporter off of a ​congressional ​balcony after he asked an unwelcome question ​– faces up to 30 months in prison at his sentencing. He is expected to lobby for probation.
