Do you have to fold here?

$50 PLO My 6th hand at the table.

UTG- $250 The reason I sat down at the table and posted early. Superfish. He doubled me up my first hand when I flop absolute nuts and just call his pot sized bets with nothing to the river. Hes playing huge pots allmost everyhand.

SB- $80 Dont know him, hasnt done anything 8 hands ive been sitting.

Hero (BB)$105 JJ24h

UTG limps, 3 other limpers, SB and Hero JJ24h check

Flop- 8h 6h Jd

SB bets $2, Hero calls, UTG raises to $4, 3 folds, SB calls, Hero calls

Turn- 8h6hJd 6d

SB checks, Hero checks, UTG bets $15, SB calls, Hero raises to $45, UTG calls, SB calls

River- 8h6hJd6d 8d

SB bets $30 all-in, Hero raises to $55 all-in, UTG calls

SB wins with quad 8's, UTG has J6xx


Notwithstanding the fact that UTG calls and gives me back my river call, is this one of those situations where you just have to bite the bullet and save 60 blinds?
