I mean it's canon so... and real relationships that last forever always (sometimes, mostly) end up being someone you meet outside of school, even if Hannah was in Hogwarts. 

To be honest, the books had very little details about Neville's love interests. And anything which Rowling has said afterwards became irrelevant the moment she declared Cursed Child as canon.

As Neville and Hannah didn't have any major interactions in the books or movies, the ship is less popular than Nuna. Nevannah still has support due to it being declared canon by J.K. Rowling. On AO3, it is the most popular ship for Hannah and the third most popular ship for Neville, behind Luna/Neville and Neville/Draco.

WHAT! Neville and DRACO?

How thE bloody hell would that work out? LOL

*Sigh* another ship to add to this book. :/

I like his canon ship - Hannah Abbott. None of the other characters seem entirely compatible with him, and though we don't know much about her, what we do know matches him well.

She's got her share of insecurities - she had a panic attack over her Herbology OWLs, and that may in fact be how they got to know each other, since Neville seems an obvious choice for a tutor (whether he offered help himself or was asked to do so by Sprout). She's also suffered loss - her mother is found dead at the beginning of her sixth year, and she was probably also hit hard by Cedric Diggory's death, given her staunch support of him in Goblet of Fire. So she could understand and empathize with him on those counts.

She's a Hufflepuff, the House he might have been in if not for the facts that 1) he needed to prove his courage to himself and his Gran, and 2) it would have been a lot more difficult to beat Nagini to death with Helga Hufflepuff's cup. But he has all the virtues of that House, and in fact becomes the powerful Gryffindor he does by applying those virtues - hard work, utter loyalty to his cause and his friends, and a desire for justice for his parents and others harmed by the Death Eaters. In turn, she has at least some of Gryffindor's courage, since she survived that hellish last year as a member of Dumbledore's Army and fought willingly in the Battle of Hogwarts. And she did it as a half-blood, and thus a more tempting target for the Carrows.

Her professions - tavern-keeper and Healer - both require a certain level of empathy, ability to listen to people's problems and offer sensible, kindly advice without overstepping, the ability to care for and accept people as they are, and the ability to comfort and offer loving care in exactly the necessary proportions at any given moment. These are characteristics that Neville, with his lonely childhood and the remaining trauma he's undoubtedly suffering from that horrific year under the Carrows, badly needs in a wife. And she's been through hell and back with him, and would need his love as much as he needed hers, thus sparing them the imbalance that would happen with, say, Neville and Luna, where he would always be the one who needed her more than she him, which would tear at his already-fragile self-esteem something awful. And she's a gentler sort of personality than Hermione or Ginny, who would both walk all over him without ever meaning to. 

It works, it really does. JKR does know her characters.

And after their school days, the two got married, although it is unknown how they fell in love. Hannah became the landlady at the Leaky Cauldron, and the couple lived above the pub. In 2014, Hannah gave up her job to train as a healer. She applied for the job of Matron at Hogwarts, possibly to be closer to Neville, who was the Herbology professor at the school. They also went to the Quidditch World Cup final that year and sat in a VIP box since they had been members of Dumbledore's Army.
