My MIL has started harassing my husband with calls and messages during work hours to try and get his attention and get him to respond to her after he stopped responding to messages. He has told her how the messages make him uncomfortable and to stop messaging him until he is ready to talk to her. His father has now got involved sending an email today during work hours even saying he can drive down and visit which has now scared me that he will. My husband and I have a problematic relationship with them after having a child and them not being interested or responsive to being involved. They then ignored me and my daughter and started to arrange visits with my husband separately away from our home so they wouldnt have to see us. My husband kept letting them know that if they wanted to see him they would have to do so with his family. They have been ignoring requests so my husband decided to focus on family here and work. The harrasment became worse after he told them to stop and put down a boundary. My husband is planning to respond to the email he got today when he is ready, reiterating his boundary to stop and that he will contact when ready. What would be the next step if this is still ignored?
