Hi there. :) I wanted to ask if any of you could give me some advice on how to deal with my bpd-so during times of acute psychosis.

When bpd hits, my bpd-so usually starts out complaining about small stuff (like not answering his texts within 5 minutes after he sent them, not answering the phone right away, etc). 

When I don't give in and don't do whatever he expects at that moment, the complaining gets worse, and he is convinced that I did it on purpose to hurt him.

And then sometimes paranoia strikes: he starts having ideas about me leaving him, me cheating on him, me already having another boyfriend on the side. None of this is real, but in his mind these ideas become absolute realities. Then he usually texts me approximately 100 texts/hour for a few hours, calling me names and threatening me. The only thing that stops him is when he gets tired and falls asleep.

I have my strategies for dealing with the small stuff (his complaints, his rants, his insecurities), but I don't have any good strategies yet to deal with these times of acute psychoses.

I tired to 
- not respond (which makes it only worse; he gets even angrier and is even more convinced that whatever he is telling himself is actually true)
- respond by telling him that this is his bpd talking (which leads to him calling me a liar, although he is aware that he has bpd)
- respond by telling him that his behavior hurts me (which makes him actually very happy in these moments; but doesn't help him snap out of it)

When he isn't able to tell phantasy from reality, I have no way of getting through to him. Is there anything, in your experience, that helps you to snap back to reality in these moments?
