Love vs. Katniss

          I believe that the fact of love itself is an antagonist in the book. Throughout the series, love is a major theme, and Katniss who had never "experienced" it, is battling it head on. She is in a crazy state of whom to choose, Peeta, the boy who had saved her and her familt's lives because Haymitch said she needed to be convinced, or Gale, the boy was her hunting partner for nearly five years, with his plan killing Prim. This problem often was brought into Katniss's mind during the Hunger Games in the cave, where she and Peeta were stayin in. She once thought about what Gale was making of all the kissing. Though it does not say right out what he does  make out of it, but I infered that he was either sick of it, or knew that Katniss was acting, since Katniss found out that they had feelings for each other in Mockingjay.
          Peeta on the other hand, seems as if he liked Katniss from the beginning when he replied to Katniss shoving him right after he confessed his love for her with "She's just worred about her boyfirend". He also showed hints of his actual love for her when he found out that katniss was acting her love for him to survive the Games, which caused him to have an angry outburst. Though Katniss, in the end, chooses Peeta, love affected the whole plot of the rebellion, so in a way, not only is the idea of love the antagonist, but also like a deuteragonist, or a tritagonist (the second or third important character in a book).
