What about the crazy harassment of ex-girlfriend

It's really annoying to encounter this kind of thing ~ if she is harassing you, destroying your family, spreading rumors outside and threatening your wife or your relatives. I think you should try to talk to her and try to solve it peacefully. If she still insists on her own way, I suggest you collect relevant evidence, such as telephone recordings, photos of you and your wife online, and rumors she said to people you know that insult your personality. Then go to court to sue and detain her if she demands compensation or harassment. First of all, if you don't solve this situation properly, it will affect your future family, including your performance outside.
