My mom had a woman she was friends with around 7 years ago. But they stopped being friends when the woman asked my mom if she could have sex with my dad. It was just crazy and bizarre and totally out there. I get that some people do that but my mom has always been open about being monogamous and made it obvious. 

Well the women moved back to her hometown years ago, but 7 years after they stopped being friends she still copies everything my mother does on Pinterest (I know right... pinterest of all places lol). For example: if mom has an idea to paint the cabinets in the kitchen gray, then this women will paint her kitchen cabinets gray. If my mom gets a tattoo or pins about getting a tattoo, then this woman gets a tattoo around the same time. She then sets it up to make people believe my mother is the one stalking HER. She has all the traits of someone with Histrionic Personality Disorder, but I’m still confused about what makes someone mimic others actions online to this extent? This woman actually posted our street address on Pinterest as well...
