$10 180 final table hand

[L_N_J]

Villain has been raising a lot of pots from this spot. I have been advised that this is maybe a push preflop but I think this is quite risky as I have people with fewer chips and am not short yet. My idea was to bet most flops and hope he folds. As played I feel I have to get the money in with overcard and flush draw. Thoughts?
