So I pitched an agent at a Writing Workshop in April of 2015. She wanted me to send her my manuscript exclusively. I agreed. She was excited! By mid June I hadn't heard back so I emailed asking for update. She wrote me back immediately asking me to be patient, that "they were working on notes". I waited somewhat patiently. A couple of weeks ago I emailed again to see if she might still be interested and still wanted an exclusive. "Just checking", I wrote. No reply. I'm not sure what to do. If she's genuinely interested in it and working on notes, I'm ok to wait. But I don't want to wait forever if I can send it out to other agents/publishers. Feels like a long time. 6 months. Is this normal? She seems like a really good agent from a good agency and she seemed genuinely into my story when I pitched it to her. Thanks for any advice.
