But sex is important. Travis was addicted to sex with Jodi. His friends knew some of the craziness that Jodi did or said but he was ashamed to let them know he was actually still seeing her. Jodi and her web ensnared the "naive part" of Travis and in the end he died because of it. His mistake wasn't telling JA he never wanted to see her, his mistake was not being strong enough to follow through on that.
