Folding nut straight on flop?

So my home game is $1-$2 no limit and we're playing Big O. Everyone has between $200-$500, typical splashy loose game.

Everyone limps for $2 and I'm in the BB with something like 6/7/10/J/J.

Flop is 3/4/5 with 2 clubs. I check to see the action.

Someone bets $15, 2 callers and then a raise to $45. Action is on me and I just fold. Everyone calls and then its like $100 on the turn and $100 on the river. Pot is split with the obvious A/2 and 2/6 for high

Putting aside the fact I would have won the high as the board ran out 9/K is this the correct fold?

I'm playing for half the pot and have to avoid a million cards to hold.
