my biggest downfall in nl

[conslice]

my biggest downfall in nl i think is that i cannot fold 2nd-3rd even4th (somtimes) nuts when my read puts a player squarley on THEN NUTS i usualy try to just get a showdown as cheap as possible and somtimes manage to fold to the big river push but the majority of the time i think im loosing money i shouldnt and its probably brinig down my bb/100hands, any advice would be great im sure this is a common problem
