tough river decision

[scags23]

75-150 four handed game on Absolute
This is my 1st hand although I watched a few rounds and SB has played lots of pots for raises and havent seen his cards. I havent played on Ab for abt a month so I have no hands with him....
Im in BB w/34 of spades folded to villian in SB he raises. I take a flop of 256 rainbow. Villian bets I call. Turn is Q of clubs putting club flush draw on board. Villian checks I bet, villian checkraises, I 3bet. River is 8 of hearts. Villian checks,I bet,villian checkraises......Whats my line?
I call or raise
