I worry about you. You're not taking any action against this harassment, and the drama continues to escalate and ruin your peace of mind. What are you going to do to protect yourself against these psychotic people and get on with your life? You've gotten some good suggestions here to block their phone numbers and texts...I'd also talk to the police and change the locks if you haven't already. Are you planning to do these things....or do you want to continue to have your life ruined by these nut jobs?
Ellima, it's really your choice, but I hope you choose to say no to it. It may give a short-term thrill but it's going to continue to rip you up inside until you end up very, very sick.
