Hi Sonia
Welcome to bpdfamily And congratulations on the health improvements you've achieved

How old is your son now? You say he has been exhibiting BPD traits over the past year and that the situation has really escalated these last two months. Did something perhaps happen two months ago that might have triggered him? Perhaps something that most people wouldn't consider a big deal but he perceived quite differently?
You say he's recently married, could that perhaps have triggered him? How would you describe the relationship he has with his wife?
I suggest you take a look at the tools and lessons to the right of this message board. I believe they can help you get a better understanding of BPD and how to deal with your son. Certain communication techniques such as validation can be quite useful when dealing with someone with BPD traits. His angry outbursts do concern me though, do you feel safe around him?
Take care
