There is this co worker at her job who called her in a secluded room and try to unbutton her pants twice with out my wife's consent, to the point where my wife had to lie about being on her period. Two separate times.
I’m sorry to hear about what you and your wife are going through. I would recommend calling the police first. If the co-Worker is charged with a crime, the police can also implement a no contact order.
Additionally, your wife may have civil remedies available to her. She likely qualifies for a civil stalking injunction. She may also qualify for a sexual violence protective order. I recommend consulting a local attorney to discuss your options in that regard.
