This woman moved cross country to move in with my sisters husband. She and my brother in law Josh had an ongoing affair, while he traveled for work.
The affair began after my sister had a miscarriage and was in a deep depression. Melissa and Josh left my sister locked out of joint bank accounts with no money, had her cats euthanized, and have been harassing her and stalking her via social media for over a year now. This woman is deranged and obviously obsessed with my sister.
