confusing fkn hand, semibluff turn, shall i fire river?

[luegofuego]

pardon me for the basic question... i guess its read based but id like some input anyway. he DOES seem kinda suspicious and calldowny, but i havent tangled with him deep before. generally, should i shove river? is the turn semibluff worthelss if i dont fire turn? there was people sweating me during the hand so i got really confused when i played it and they yelled a lot of different stuff. i WOULD play sets this way a decent amount, but he doesnt know it.
