1) Reads/stats help... Is he raising low pps there preflop? Basically he either has a FD, a total bluff (which may still have a lot of outs) or you're crushed. Time to GTFO.

2) No. You cannot flat call preflop and then go broke on a low flop. If you want to go broke here then 3bet preflop (3bet preflop anyway vs. most.)
