Hi! I queried an agent back in December and on the 17th she asked for an exclusive on the full manuscript, which I granted (I know now that's something you shouldn't do lightly but she responded to my original query quickly and I'm pretty young and new to all of this). After three or so months I sent her a follow up email, and then about month later I sent her an email in which I explained that I couldn't keep it under exclusive and started contacting other agents. It's been six months since I submitted the manuscript with no reply. I know things move pretty slowly in this industry but should I take her silence to mean she has no interest in my work? Thanks!
