Serial cheater on the apps

Her name is Emma/Emily. Age 25. Dark brown hair thick bangs brown eyes pale to tan skin. Golden retriever dog. I have 1,000 risqué pictures of her off his phone and I know her last name and all her friends and family and her workplace but I don’t want people to harass her, I just want to save someone from the same fate as me. She was my now ex’s ex, she cheated on him but they both continued to sleep together and cheat on their partners over the years. She knew about me for 3 years but still kept seeing him, when confronted did not show remorse. They didn’t use protection and I never would have guessed that the weird symptoms I was having was an STI wreaking havoc on my insides.
