I've been building a great relationship with a wonderful man over the past 6 months. On two occasions, we've run into his ex-girlfriend. This lady causes drama and chaos each time she sees us. She somehow found my phone number and after seeing us, she calls me repeatedly leaving foul threatening messages on my voicemail.
Neither he nor I know what to do to get her to stop. Can you offer some advice?
This "lady' you describe is no lady at all.
First off, it's completely inappropriate (not to mention psycho and unattractive) for her to make a scene when she runs into you and your boyfriend. Furthermore, calling you repeatedly and leaving threatening messages is harrassment and could land her in serious trouble with the police.
The next time you or your boyfriend talk to her, warn her to knock it off, or you will report her to the police. If she doesn't back off, please do report her and ask an officer for specific advice on how to deal with her if she rears her scary head again.
