NaruSaku fans need to get over it. Sakura, like most women in the real world, aren't attracted to the guy who is most available to them. They go for the opposite, what gets her eggs hot, and selection/discretion in that context is proportional to her choices and self-worth.
Most women can't help that any more than most men can't help being horndogs. It's how both are biologically wired and socially conditioned. Deal with it, dattebayo.
It is funny to watch Sakura deliberately cuck Naruto by deliberately excluding his presence. I think she's bitter about him turning down her fake confession. She was thinking, when making the confession, "pfft. I got this boy around my finger".
