Carmelo Anthony’s discontent with the Knicks organization became so severe after Monday night’s loss to the Bulls, he told a confidant he preferred to be traded before Thursday’s NBA deadline, The Post has learned.

According to a person familiar with his thinking, Anthony’s disillusionment stems most from a belief coach Mike D’Antoni and interim GM Glen Grunwald do not trust him. He is surprised that after all the Knicks gave up to trade for him, he has not been asked for more input on personnel decisions, as Deron Williams has with the Nets.

“The organization makes believe his opinions don’t matter,’’ the source said.

However, Tuesday night, a source said Anthony and D’Antoni spoke in an attempt to reconcile their differences and made headway. On Monday night, Anthony only wanted to remain a Knick if he had assurances D’Antoni wouldn’t be back next season.

However, Anthony will not make a formal trade request.

As The Post reported Tuesday, Anthony was told after the Knicks were swept out of the playoffs by the Celtics last April that D’Antoni would not return for this season.

But now Anthony does not believe a decision on D’Antoni’s future is coming soon because D’Antoni and Grunwald, according to the source, are “like a couple.’’

Anthony was unavailable for comment Tuesday as the Knicks did not practice. It is against NBA rules to publicly state a desire to be traded.

According to the source, Grunwald has had just one conversation with Anthony since he became GM. And D’Antoni rarely talks to Anthony after games, especially since Anthony’s return from a groin injury. The Knicks have lost 8 of 10 games since then to fall to 18-24 and out of playoff position.

Anthony is not close to owner James Dolan the way Amar’e Stoudemire is. The source said Anthony gets along best with assistant GM Allan Houston, who eventually could succeed Grunwald.

“He knows Glen doesn’t like him,’’ the source said.

It would seem unlikely — and ill-advised — for the Knicks to pull off a trade for Anthony on such short notice before Thursday’s deadline.

Though Stoudemire lobbied for the Knicks to trade for Anthony, the pair’s friendship has not flourished.

“They’re not as close as people think they are,’’ the source said. “It’s an awkward relationship.’’

Anthony is not jealous of Jeremy Lin’s global fame, according to the source. Lin, the source said, is Anthony’s favorite teammate, and Anthony feels they could be like the Thunder duo of Kevin Durant and Russell Westbrook.

According to the source, when Nuggets general manager Masai Ujiri tried to convince Anthony to stay in Denver last season, he repeatedly told Anthony he never would be able to handle the New York media. But Anthony believes the media has been the least of his problems and wished there was more feedback from his superiors.

Anthony has endured a poor season, shooting just 40 percent from the field while averaging 21.3 points and has not played well recently on defense.

D’Antoni rarely speaks in the same reverential tones about Anthony as he does about Lin, Stoudemire and Tyson Chandler.

When D’Antoni was asked after Monday’s loss to the Bulls if Anthony looked frustrated, D’Antoni replied, “More than normal, you mean? I don’t know. You’ll have to ask him.’’

Anthony appeared agitated on the court during the game and failed to join the huddle after the third quarter, though he said that is not uncommon. Though Anthony has expressed concern about his role in the offense, many play sets contain Anthony post-ups.

Anthony seemed extremely unhappy after the Knicks’ losing streak reached six games in Chicago.

“It [stinks],’’ Anthony said. “The situation we’re in right now [stinks]. Losing basketball games the way we’ve been losing games at the end of the game [stinks]. It’s not a good feeling right now.’’
