“If you are reading this, I am no more,” the accused killer husband of Connecticut housewife Jennifer Dulos began his suicide note, obtained on Friday by The Post.

“I refuse to spend even an hour more in jail for something I had NOTHING to do with,” wrote luxury home builder Fotis Dulos, Jennifer’s estranged husband, sometime before he rigged a vacuum-cleaner hose to fatally fill his Chevrolet Suburban with exhaust fumes.

“Enough is enough,” he said in the note, which was recovered inside the car. “If it takes my head to end this, so be it.”

The Greek developer, 52, was near death when he was found inside his car on Tuesday and was declared dead Thursday night at Jacobi Medical Center in The Bronx, where he’d been rushed for specialized treatment for carbon monoxide poisoning.

The note he left behind was neatly hand-printed in blue ink on a single sheet of looseleaf paper.

It was dated “1/28/20” the day he was found near death in the car, which was inside the garage of his sprawling brick mansion in Farmington.

Tellingly, it has no words of kindness for Jennifer, with whom he had five children ages 8 to 13 in common. It mentions her only to insist that neither he nor his two co-defendants, former mistress Michelle Troconis and attorney Kent Mawhinney, had anything to do with “the disappearance.”

Of his three sons and two daughters — now being raised by Jennifer’s mother — he wrote: “Please let my children know that I love them, I would do anything to be with them, but unfortunately we all have our limits.”

Jennifer vanished without a trace on May 24, after dropping the children off at their private school.

But the suicide note speaks directly, and tenderly, to his latest girlfriend, identified by The Post as Charlotte-based financial consultant Anna Curry — an attractive brunette who bears a striking resemblance to both Jennifer and Traconis.

“I want to thank all my family and friends that stood by me this difficult time,” the note ends. “Above all Anna Curry. I am sorry for letting you down and not continuing the fight.”

The note, addressed to “All,” ends simply with the printed name, “Fotis.”

Dulos had been free and under house arrest on a $6 million bond that was partly financed by Curry. He was charged with kidnapping and murdering Jennifer.

Ex-mistress Traconis, 44, was charged with conspiracy to commit murder, as was Mawhinney, a close friend of Fotis who’d repped him in a civil suit. Their cases will proceed despite Dulos’ suicide.
