MEG RYAN is no “Small Town” girl – and John Mellencamp is not about to put down roots in the concrete jungle.

Sources say that the lovebirds, who have been dating since 2010, hit the skids because country boy John hates New York and Manhattan Meg refuses to move to the heartland.

“Meg and John were headed toward engagement and mar­riage at one point, but not anymore,” revealed an insider. “John would be happy to keep a long-distance relationship going, but that’s not enough for Meg. For now, she’s done with John. She didn’t even in­clude him on her New Year’s family trip to Aspen.

“She’s chosen New York, he’s chosen In­diana, and neither is budging on the reloca­tion issue.”

According to an insider, John, 62, has begged Meg, 52, to pack up and move into his mansion in Bloomington, Ind., but she won’t even consider it.

The “When Harry Met Sally” actress – who hasn’t starred in a film since she appeared in the 2009 black

comedy “Serious Moonlight” – is about to start shooting a TV pilot in New York. She also has two kids – adopted daughter Daisy, 8, and Jack, 21, her son with ex-husband Dennis Quaid – who happily call the city home.

Meg and John got to­gether shortly after his split from model Elaine Irwin. Since then, he’s been making frequent trips to New York to keep the romance from fizzling.

But the rocker torpedoed the re­lationship in early December when he told an interviewer that moving to New York was out of the question because: “I can’t see poor people. I can’t see the suffering. I can’t see the trash on the streets…I’m not leaving Indiana. I’m going to die here.”

 Added the source: “John’s home base is just outside Blooming­ton, where he owns a lakefront mansion at the edge of a wooded 65-acre estate. In addition to being a musician, John is an artist and has both a recording and art studio on the property. He owns several businesses around Bloomington and is happy being a country boy. He hates the big city.”

MEANWHILE, back in the Big Apple, Meg is very anxious to make her acting comeback. In the new series – which she also produces – she’ll star as a single mom who returns to the New York book publishing world following a long absence.

“Meg left Hollywood years ago for Manhattan,” the source added. “She’s not about to leave the life she’s made there.”
