If I think of an overview of Sasuke's feeling towards Sakura. He probably hated the fact he was stuck with one of the random girls that used to fawn over him, but at least felt she was better than that idiot Naruto because she had good grades. Then, after the bench talk he thought she an annoying spoiled brat that doesn't appreciate what she has. He also thought once he gotten to know Naruto more and respect him. That she wasn't doing enough compared to Naruto and that she was worse than Naruto despite initially being better than him. Eventually, with time spent on team 7 she became one of the few people Sasuke cared about which allowed her to help him suppress the curse seal when he looked into her terrified eyes. However, those feelings didn't not outweigh his desire for revenge nor did she understand him enough to keep their bond from severing at the end of part one like Naruto was able to.
After that she became an annoyance that he would kill without hesitation if she got in his way. Also as his before final battle rant said; he doesn't get what she actually likes about him because he has never showed her any affection, and think she delusional even living in a dream world if she think he would ever love her. Then, out of guilt, and to appease Naruto; he ended up with her.
The one time he ever said anything nice to her or about her. Was during the chunin exam because he could tell she was depressed, realized that he probably was going to work with her to pass the exam at some point, and so he needed to restore her confidence...which he originally destroyed in the first place.
The person that has complete faith in her and constantly praises her was Naruto. So the manga is awkwardly making Sasuke fill in the Naruto role in Sakura's relationship, just like Hinata has to be Sakura-like in Naruto's. Which again is because neither couple interacted that much in the manga so eventually they have to go back to a relationship that did NS.
