Nah, she totally read him wrong.

Eren feels inferior and just really wants to kill titans. He wasn't even interested in what Mikasa had to say about his future.

Mikasa on the other hand just wanted to be with Eren. She thought he was worried about being separated from her (and assured him she'd leave with him if he couldn't make it), but really she just thought it'd be lonely without him. In the end, she only joined the forces because Eren joined.
