To offer some funny insight into their relationship BPD 2 strangled BPD 1 in a field when they were 16 to the point where she fell almost unconscious, I've had this story told to me by them both at different times without bringing it up. Also Number 1 went out with number 2s ex and proceeded to get pregnant and have an abortion, though number 2 is convinced she's lying about this to this day. They never liked eachother just became semi friendly around a year ago as they both have private "Vent" accounts on Insta and number 2 made a post saying she'd just been diagnosed which got them talking, not super relevant but of all the people for me number 1 to see a picture of me with in the whole entire world that would probably be her last choice. Also I don't mean any disrespect by saying 1 and 2 etc but it just seems easier until I can think of something better
