how would you play?

[grinder2]

Iam at a 1/2 nl cash game $100 min. I have $100.00 in front of me. I have never met a single person playing at this game before. Plenty of action, lots of good hands and a good varity of players from tight to loose. I have taken some small pots by a few continuation bets and have lost a few and folded more. The big stack is sitting to your left and has played some, but not many hands and has won most of them with good starting hole cards that he was raising preflop and hitting them. Iam on the button and I was delt QC, 10C. Everybody folds to me. I bet $6.00 and the small blind calls. QD, JH, 6C hits the board. I bet $15.00, BB just calls. 10S hits 4th. Iam two paired but a posible straight is out there. I check, he bets $15.00, I call. 8S on the 5th. I check he bets $35.00, what do you think I should have done?
