He didn't forgive his brother and continued to resent him for years, despite Albus's immense feelings of regret, of which Aberforth did not know until Harry revealed it to him, which allowed Aberforth to finally forgive his brother. That same summer, Aberforth fell in love with a girl from Godric's Hollow.
Aberforth never forgave his brother until years later, after Albus's unfortuante death at the hands of Severus Snape (Who was actually working on Albus's orders), when Harry informed Aberforth of his brother's regret.
During that summer, Dumbledore had neglected both his brother and his sister and Aberforth soon let him know about it. Aberforth was set to return to Hogwarts and was fed up with Dumbledore's plotting with Grindelwald – in addition to being concerned about Ariana's care.
There were many attendees of the funeral. Aberforth Dumbledore, who was Albus' estranged brother and barman of the Hog's Head Inn, a delegation of Ministry officials, including: Cornelius Fudge, Rufus Scrimgeour, Dolores Umbridge, and Percy Weasley.
Dumbledore tells Newt Scamander (Eddie Redmayne) that in 1899, during the same summer that Albus fell in love with Grindelwald, Aberforth also fell in love with a woman from Godric's Hollow. They had a baby boy together, but the woman was sent away before she gave birth, and Aberforth never got to be a father.

Why did Aberforth abandon his son?
Aurelius was an illegitimate child of Aberforth's. His mother is killed, and as a result Aberforth is unable to care for his son. Credence is taken to America and put up for adoption, a fact known to no one but Leta Lestrange (Zoe Kravitz).
Aberforth's son is Aurelius Dumbledore, born after he fell in love with a girl in Godric's Hollow. However, the girl was sent away, either before or after Aurelius's birth. His son was adopted by Mary Lou Barebone and renamed Credence Barebone. Despite the rumors, Aberforth never confided in Albus about his son.
Harry recognizes the man's blue eyes as those he's been seeing through the magic mirror, and he realizes that this man must be Aberforth, Dumbledore's brother, and that Aberforth was the one who sent Dobby.
Fantastic Beasts 3 reveals that Credence is Aberforth Dumbledore's illegitimate son. Since Grindelwald was telling Credence the truth about his name being Aurelius Dumbledore, it seemed logical that he's one of Albus Dumbledore's siblings.
Although Aberforth was a brother of Albus, he did not study the art of magic as much as Albus did. He cared more for the Dumbledore family than Albus did and abandoned his studies to help them out. He was powerful, but not quite as powerful as Albus.
Patronus Charm: Aberforth was capable of summoning a fully formed Patronus which took the form of a goat. Dueling: Though not as powerful as his brother, Aberforth was nevertheless a talented duelist being able to survive the Battle of Hogwarts, defeating Augustus Rookwood in the process.
Aberforth met Credence's mother the same summer that Albus and Grindelwald met. Now, while living as part of Grindelwald's followers, Credence began to write messages to Aberforth through a mirror because he was desperate to come home – though to begin with, he didn't know he was writing to his father.
'You sent Dobby. ' The barman nodded and looked around for the elf. Second save: He covered up for them when they accidentally set off a Caterwauling charm while apparating into Hogsmeade.
At the age of six, she was seen practicing magic by a group of Muggle boys. When she was unable to show them how to do the same thing again, they violently assaulted her. The attack left Ariana emotionally scarred and unable to control her magic.
Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
Really though voldemort would have killed him easily, as could many of the death eaters I suspect. He isn't is brother and never had any interest in being like him it seems. Aberforth himself seems to know it, having given up the fight by the time Harry meets him.
To defend her students, McGonagall casts a series of spells Snape's way, but he manages to evade all of them before flying away. But what McGonagall doesn't know is that Snape is actually a double agent working for Dumbledore, so he has no intention of harming her.
According to Queenie, Leta was a "taker" rather than a "giver", and she did display a selfish streak throughout her youth: Leta swapped her baby half-brother Corvus for another infant simply because she couldn't tolerate his crying; at Hogwarts, she allowed Newt to take the blame and be expelled for her own childish ...
Fantastic Beasts: The Secrets of Dumbledore confirmed that Credence Barebone/Aurelius Dumbledore (Ezra Miller) is the new Snape (Alan Rickman) through a very familiar line delivered by Aberforth Dumbledore (Richard Coyle). Fantastic Beasts 3 finally shed light on the Credence being Aurelius Dumbledore plot twist.
Harry asked for help while looking at a two-way mirror; Aberforth had the other mirror. He sent Dobby to rescue them; the house-elf did so, stating that "he would always be there for Harry Potter", but was killed by Bellatrix Lestrange.
Assuming it is the case, evil nature of Nagini's snake half who later joined Voldemort is easily attributed to the loss of humanity which ended up in her human half reminiscent to Urizen who bereft of his true self Vergil's humanity which ended up in his other half V.
Since Harry was looking at the mirror shard before Snape's Patronus appeared, and the inside of the Hog's Head was seen, the most likely explanation is that Aberforth was working with Snape, and that Albus may have told him of Snape's true allegiance before he died.
