BKiCe ???

this is more of a general question, i find myself in spots like this often when i three bet preflop heads up... what's the best line to take here? should i think about checking flop? it just seems like i get blown off so many draws in hands like this where i reraise preflop, flop a draw, get reraised where i feel i have no fold equity but at the same time aren't quite priced in. villain and i just started playing so i don't have much in the way of reads.
