I'm in a 1.5 year long affair, and we made a sex tape at my apartment. One week ago, his wife found the sex video at his house, and in an emotional frenzy, she changed the locks to their house so he cannot have access. The house title is in both their names. She threatens to use the sex videos against him in court if he tries to re-enter. They're divorcing now. They have a son. The son was not around during sex video. The sex video depicts us having sex on my couch (nothing that exciting and certainly nothing illegal). His wife is a successful insurance/medical malpractice attorney, and her father is a retired attorney and legal mediator. Her father warned my lover, "you will not find a judge in the state who will give you access to your house with those sex videos." Is this legal for her to use our sex videos against him? Also, are my privacy rights being violated that she has my sex videos and threatening to use them in court? This is in Washington, which is a no-fault state.
