Katniss doesn't relize it at first but she loves him more than gale.
He is the clueless bakers son, that is chosen to go along with Katniss to the Hungergames. Later he falls in love with Katniss. Actually he is already in love with her, its just that they never talk to each other much before the games. Later is when they become friends, enemies and something more
Peeta gave Katniss bread when her family was starving. It was the favor that meant so much to Katniss. Peeta gave her the bread because he loved her, even then when they were young.
Katniss wasn't really in love with Peeta when they kissed in the forst movie. It'll get much more complicated in the 2nd movie, hopefully comming out November 22, 2013.
Isn't it obvious? He loved Katniss so much that he did anything to save her, he has a great heartand cares for people, if you read the book you'd understand. I LOVE PEETA.
They shared Peeta's crush on Katniss on TV right before the hunger games to make them stand out. At first, it may not have been true. Saying that they were in love made sponsors interested in keeping them alive and made the Capitol love them.
**This answer will contain spoilers! Don't read unless you're not planning on reading Hunger Games, Catching Fire, or Mockingjay!**Throughout the story Katniss is never "with" Peeta, it is mostly an act. In Catching Fire, Peeta stages a proposal for the capitol and she says yes, but later they break this off because they're busy escaping from the capitol.
Pretty much both
I don't want to say too much, but in catching fire (second book) peeta gets captured and in mockingjay (third book) he comes back with a brain chip that tells his brain to relate anything bad to katniss. But he snaps out of it so yes and no.
When Peeta get hijacked by the capitol he loses his memory and now he only has bad memories of Katniss and tries to strangle her. The doctors try to unhijack him by putting good memories of Katniss back in his mind. Soon he comes back from the Doctors to District twelve. He and Katniss grow back together and at the end when they are in bed Peeta wispers "You love me real or not real" Katniss says real. They get married and have two children together. But Peeta has always loved Katniss.
Peeta was asked to lift objects and throw them around. He felt that the game makers were not paying much attention to him. Peeta scored an 8 in his private session and Katniss scored an 11.
This book is filled with so much suspense! Here are only a few examples that you can translate any way you need to... Book 1: Will Katniss win the games? will she sacrifice her life for Peeta or another tribute such as Rue? Will Peeta die of sickness? will the careers kill Katniss? How will Gale feel about Katniss, if she returns from the games with Peeta? Will Katniss be punished by the capitol for rebelling? Book 2: Will Peeta forgive Katniss for pretending to fall in love with him so they could both win the games? will Katniss actually choose to love Peeta or Gale? What happened to Peeta as he was taken by the capitol? Will Peeta kill himself to save Katniss or vice-versa? Book 3: Will Katniss ever get Peeta to love her again? What happens to Prim? What will happen with Annie and Finnick? Does Peeta remember how he loved Katniss so much and will he ever be able to love her again? What happens between Katniss and Gale? Do Katniss and Johanna ever become friends? Does Katniss really love Peeta? Not all of these examples have to do with straight up action but they all keep you guessing!
its because the capitol hijacked his memories and its makes him hate katniss. The Capitol hijacked Peeta's memory about Katniss and is supposed to think she is his enemy and has to kill her.
