I feel kinda bad for Peeta. In the first book, he actually thought that Katniss loved him then, he was heartbroken when she the whole thing was fake. Then in the second book, when Katniss started catching feeling right when they were going back into the hunger games he was probaly very confused. Then finally, when Katniss is in love with him he gets highjacked. THEN when he gets better Katniss is like i've changed my mind I don't want him anymore. But finally, towards the end of the series they both love each other and they rest is history.
