Facing River bet

[natarish]

last weekend i was playing 5-10 NL live at local casino. i have had two bad beats in a span of 5 hands and i was stuck 4.5K. After 3rd bad beat, i was down 5.5k.

Bad Beats: 1st: Flopped straight and villian rivers boat with his two pair.
2nd hand: turn flush and villian rivers boat with flopped set.

Anyways here's the 3rd bad beat in a span of 15 hands. Full Ring game with $20 straddles.

Villian: MP1 Stack: 4K VIlians is very loose aggressive player: Plays over 3rd of the deck.
Hero: Button: 2.5K

Villian opens for $60 and it folds around to me and i call with AQs on the button.

FLOP: Pot Size: $150 8c 9d Qh

Villian checks and i bet $120 into the pot and he instant calls.

TURN: As
Pot Size: $390

Villian checks again, I bet $290 into the pot and he calls again.

River: 8d
Pot Size: $970

Villian leads fro $750 into the pot and i go into tank. I showed him my hand while tanking for almost 2-4 minutes. He gets off his seat and keeps cracking up how he has rivered me and kept apologizing for rivering me and kept laughing. i refused to beleive him and call.

I think he probably rivered you again given his reaction unless he is really calm and collected when running a bluff there. Furthermore I dont think its a spot where he is ever lead bluffing very much so it looks a lot like TJ slowplayed, 8x w/ a straight draw from the flop, or a worse Ax two pair. I'd probably fold readless

I'd call his line for value just doesn't make too much sense. I could even see him having AK or something, TT, 9Ts, JJ. Unless you have reads he likes to slowplay his big hands I don't think he has enough value combo's that play this way to fold. Also his reaction about rivering you seems more bluffy to me, if he had it I don't think he'd want to create such a stir, almost seems like he's trying to level you into folding since he knows he's beat, but it's hard to say.
