I think she gets a lot of bad publicity because since we only see through Yamato's eyes when they are/were together all you got was the bitchy Suzuka. I think she had an elementary way about handling relationships (this was shown with Tsuda and to an extent Yamato), but with Yamato it was more of a psychological barrier of having the happiness of liking someone who you know liked you back taken away from you. She didn't want to put herself in that position again where it had the possiblity of happening again so she pushed the person she liked (no matter how much she denied it) away.
