Thanks MM and Tuuli! No, the other agent is not asking for an exclusive...
Hmmm--I've gotten confused before on the exclusive vs. non-exclusive definition. When I queried Meredith I told her that other agents had partials/fulls and she promptly declined reading my full "until the other agents were done with it," so I'm assuming(?) she didn't want me to have ANY other partials or fulls out when submitting to her. Which I'm fine with. But, like I said, I've painfully waited, clearing out my submission responses so I could get back with her, and now I can't get a response from her.
It may be that she is just not interested anymore, which is fine, or maybe she's swamped. Again, no problem--It's just that I've been debating whether or not to avidly resume querying (and also whether to submit this other back-dated partial request...)
But I think you've helped me, Tuuli. If she didn't mind YOU having other partials out, then maybe she meant the same for me--? I'll consider submitting this partial to the other agent, but if Meredith gets back w/ me I'll still give her exclusivity (or what I think exclusivity is, anyway).
