No, she didn't. She was head over heels for him to the point where her entire character and personality revolves around him.
Eren was too retarded to realize that. Also, he treated her like shit for the entire series, and made literally no attempt outside of that one during the Marley Arc to remotely try to express his feelings for her, and then fucking told her he always hated her. Had he actually just straight-up told her the truth, Mikasa would've been fucking over the moon, and on his dick in an instant.
Nothing happened with Historia. It feels like something was supposed to happen with them, but Isayama changed his mind, or whatever.
