2 pair facing bet/3bet line vs donk. WTF??

[LucidDream]

Villain is a donk. He's 40/4/.5 but he has been much more aggro on the turn and river than his TAF stat indicates. He is on my left and has been firing a ton on turns and river forcing me to lay marginal hands down. Making really weird bet sizes, sometimes very small and sometimes huge overbets.

Looking for comments/advice on my river raise and what to do now. I raised to get value out of a smaller A or smaller 2 pair when he blocks the river. He instashoves AI on me.
