Final Pot: t5530

He did have JQ for the nuts on the end, but will a raise on the flop or turn have pushed him out? I nearly just called his river raise thinking that by calling the first player would call as well, putting more money in the pot for me than if i reraise, where if i get a call i am probably beat, and by reraising i am committing myself to the pot. what would you all have done here?
