I have a dear friend who has BPD. Every so often, he'll give me the silent treatment after we have an argument about something. This usually lasts about two or three weeks and then everything goes back to normal. My question is, how should I act when he gives me the silent treatment? In the past, I've just continued talking to him like usual. I say hello and ask how he's doing, but I get the impression this just annoys him. I was thinking about not saying anything to him, but I'm concerned that he'll interpret this like I'm the one giving him the silent treatment, and I don't want him to feel like I'm abandoning him. Does anyone have advice for dealing with this situation?
