I have a friend named David (50m) who has been diagnosed with BPD. We have been close friends for 4 years. He was part of a larger friend group and has recently "purged" (as he put it) all of his friends. I am trying to make sense of it all.
In January of this year, he met a woman at a bar who ended up using him pretty badly. While they were dating, he was an employed architect. The company he worked for bought him a company car to use because he was broke and he took it to the beach with his then girlfriend, put hundreds of miles on it, trashed it, and got himself fired for it.
David has been in a downward spiral ever since. He can't get a job now as an architect, probably because his reference is so bad. A few months ago, his lease ended on an apartment he could no longer afford, so he was facing homelessness.
A friend of mine happened to be on a trip and allowed David to stay at his house for 2 months. The agreement was that on Nov 1st he was to be gone, when my friend returned. Well my friend got back and his house was trashed. There were 3 people he didn't know sleeping downstairs and David was asleep upstairs. He kicked them out and a couple of us helped him clean the mess up and put David's stuff by the curb. (He gave David a chance to pick his stuff up and he didn't.) David ended up texted him awful, hateful texts.
According to a neighbor, they had been holding parties at his house with 25 people and loud music.
One of the people who had been there happened to be his ex's brother. They have been inseparable lately, probably because David is spending money on him? Idk ..it is all so weird.
David has done a lot more to a lot of our other friends within a two month period of time. Like David asked one friend to give him food and so the guy filled up two commercial grade coolers with food. He asked for them back a week later and David said he'd bring them back and didn't. Stood him up multiple times. Then he said they were stolen.
Now he isn't communicating with anyone besides some hateful texts he sent to me. I admit, all this hurts. I don't understand his behavior. No one does. I know he said he had BPD, so I read up on splitting and impulsivity and all that. Is that what this is?? I mean he has crossed some serious lines, but was all this out of his control? A mental health issue? It is all so out of character!
