Bf left my daughter and I for a slut who sent it nudes within a week of working together..he send us away, deleted his Facebook and none knows we exist. Should I message her to say "hope you make him happy since he left a family for you" "do you always send nudes to men with family's" I want her to know he had a family and left us for her... What should I do or say?? Kills me to know she dosnt know or maybe she does and just dosnt care she's a slut.. 😢😢
