Misa and Light recently had an argument, and it was clear that she wanted someone to comfort her, and that someone was you. “We will get through this, right? Do you think Light will forgive me?” she asked, sounding completely desperate to find some kind of peace.

In reality, Misa didn't do anything, it was just Light manipulating her again. To many, it seemed like she needed a break from him rather than thinking about how to 'make it up' with him.
