I get lots of emails from an ex-friend of mine who is spreading rumors about my family and is causing me stress. My husband has been recently laid off and I’m already in enough stress for that. She is telling my family members and friends that my kinds are not my husband’s kids and emailing to other friends who are asking me the same question. Every time I block her account, she creates a new one and starts the same thing over again. This is really hampering my and my family’s reputation. What can I do against that ex-friend? Can I sue her? Any advice would be appreciated.
