Sean Combs: Cross-examination of Cassie Ventura begins.

The defense showed Combs's ex-girlfriend texts where she appeared to be a willing participant in drug-fueled sex acts. She testified that in the early days of their relationship she wanted to make him happy, but later feared his anger if she said no. Ventura also admitted to jealousy over other women Combs was dating during their 11 years together, but said Combs's jealous rage turned into violence, such as when he found out she was dating musician and actor Kid Cudi. Allegedly he kicked her in the back and later blew up Kid Cudi's car.If you want to read NBC's coverage of the trial, check out our newsletter, “Diddy On Trial”: NBCNews.com/Diddy
