your behavior is affecting him, and his is changing. He is testing still.
When he claims that it kills him to see you sad you can just tell him it's fine to get his stuff. He's hanging on by dragging it out. By you not correcting him and saying your fine, his assumption of your sadness is confirmed.

Why are we humans so messed up...
