The problem was that Gale was the one who created the firebomb devices. Despite not being fully responsible, Katniss couldn't overlook his possible involvement. Katniss returned to District 12, where she reunited with Peeta after she couldn't allow herself to fully forgive her childhood best friend.
In the end, Katniss and Gale grew apart, as many childhood friends and young loves do. She needed something different in her life, and with Gale's link to Primrose's death, Katniss found a reason to cut ties.
Katniss's focus on survival and her family's safety prevented her from fully considering romance, but her feelings for Peeta and Gale diverged in the end. Katniss ultimately chose Peeta because he understood her trauma and she didn't want to lose him, proving her love for him.
She understands that Gale is more than a friend to her but can't admit that she has romantic feelings toward him. She recalls their time in the woods, how she is a better hunter when he is there with her because she trusts him. They depend upon one another to survive and to provide for their families.
In chapter 14 of Mockingjay, Gale embraces katniss to kiss her, she kisses Gale back, not because of desire but because she feels like she owes him these kisses and she's lonely.
Hunger Games: Why Katniss Ends Up With Peeta, Not Gale
Why does Katniss kiss Gale so much?
When Gale is most in pain is when Katniss kisses him, and this is true again as we see her answer Gale's pain with a kiss. She wants to give Gale what he wants, but she can't yet completely commit to him, as she must think of her family and Peeta and being the Mockingjay for the revolution.
Even though the order to use the bombs was given by President Coin, Katniss cannot bring herself to forgive Gale for his creation and his role in Prim's death, and effectively shuts him out of her life.
Although she will never know for sure, Katniss does recognize that she cannot be with Gale. She will never be able to forgive him for his idea — the parachute bombs — that killed Prim.
Gale is jealous of Peeta and the relationship he has with Katniss, and he wants Katniss to decide between them, though he doesn't press Katniss during her recovery in District 13. Gale is an excellent hunter and excels at setting snares and traps.
He Didn't Save Peeta's Family But some people believe Gale may have had more malicious reasons for not helping them. However, Peeta's family wasn't great. His parents were abusive, or at least distant. It would have been interesting to see what would have happened had his family survived, but no one missed them much.
Before the Capitol battle, Gale had explained to Katniss his series of bombs designed to feed off human compassion: a small bomb would go off, and then when medical aid rushed in, a second bomb would go off, killing those people as well. Incidentally, it's this exact type of bomb that took Prim's life.
Gale does not marry anyone in The Hunger Games. He and Katniss talk about running away together and starting a new life in the wilderness, but they never officially marry.
Ultimately, in Mockingjay, it was undeniable that Katniss was completely in love with Peeta. Even though both Gale and Peeta are great men who wanted the best for Katniss, there's no doubt Peeta was kinder, and more loyal and understanding. These qualities made Peeta way better as a character and as a love interest.
Gale is neither truly friends nor enemies with Peeta Mellark though he has felt jealous of Peeta due to the show that Peeta and Katniss put on for the cameras.
Gale's jealousy towards Peeta stemmed from his feelings for Katniss and his desire to be with her. Even after Katniss became engaged to Peeta, Gale still harbored feelings for her and was unable to fully let go of his jealousy and resentment towards Peeta.
At the end of Mockingjay, Gale relocates to District 2 and begins working in the district's government. He helps train replacements for the Capitol's Peacekeepers.
The woods are now ruined. Katniss decides that the Capitol views her and Gale's weekly hunting trips — and the one time that Gale unexpectedly kissed her, which Snow knows about — as flaunting her defiance in front of the entire district.
Peeta used the dyes to paint a picture of Rue after Katniss covered her with flowers when she died. He says he wants to hold them accountable for killing Rue, and Effie tells him that that kind of thinking is forbidden. Katniss then tells the team she hung a dummy of Seneca Crane.
Protagonist Katniss Everdeen has two suitors: Peeta Mellark and Gale Hawthorne. Some people prefer strong, hot-headed Gale, while others prefer kind, charismatic Peeta. When one closely examines both options, however, it becomes obvious that Peeta is the superior love interest.
Katniss speculates that Coin deliberately sent Prim to die in the Capitol bombing in order to fully gain her trust, but it's never outright confirmed or denied.
It's only implied that they get it on via snuggling and other affectionate acts in close quarters — but if you have read the book, they really imply that they took their relationship to the next level.
In Mockingjay, Katniss asked her long-time friend to kill her after she assassinated President Coin instead of President Snow. Whilst Gale's wish for death was because he wanted to avoid becoming the Capitol's puppet, Katniss' is more to do with depression and not facing the consequences of her actions.
Prim was among the medics who arrived to treat the victims. Unfortunately, a second batch of bombs were set off, with Prim being killed in the explosions. Gale was not the one to drop the bombs from the hovercraft, but he was one of the key figures to devise the strategy of double bombings.
According to the star behind Effie, Elizabeth Banks, she and Haymitch's Woody Harrelson improvised the scene. Considering she's been adamant about the characters having some romantic connection, it only makes sense that they'd share a goodbye kiss. It's very on-brand for Effie, as well.
Peeta, Annie, and Beetee vote no, while Johanna and Enobaria vote yes. After some thought, Katniss demands to kill Snow. Once she receives an agreement, she votes yes, for Prim. Realizing something is up (as Katniss would never do that), Haymitch votes yes, too.
