Requery? (interesting circumstances)

Quick Recap.

I queried an agent, received a full request the next day, sent it. Waited.
3 months later, I status queried and got a "still considering" respose.
3 months later, I status queried and got no response.
1 month later, I status queried and mentioned another book. Received a rejection for the first and partial request for the second.
1 week later, received a rejection on the partial.
1 month later, queried with entirely new and different project (different genre, too)

This was late November. No reponse so far. This agent usually answers pretty quicky to everyone (for queries at least) and has been active in the past month. Should I assume, at his point, that the agent just doesn't want to work with me and move on? Or should I wait and either send a query for a new work in 2 months, or requery work 3 (under the assumption that the agent didn't get the first email)?

Any advice/opinion is appreciated!

After I made that timeline, I started wondering why I was trying to query this agent again, anyway...

And all other partial/full rejections I've had cited pretty specific choices I made, and would rather keep, in the manuscripts. I also send a set number of queries, then move on. I guess I could go back and revise and send other queries, but I'd rather work on new things, generally.

But, I think you're right. I think I'll just move on.

Thank you!
