I want to write a letter for a friend with bpd to try and communicate about a issue hopefully for the last time.

Everytime i tried this before he either, didnt read all the letter, got annoyed because of me being insecure or anxious or told me to just drop it.

Everyday it gets worse, he just finds me annoying and is mean to me almost always, shorter replies and no care for me as a person.

I think its the end now, no matter what i do i think he will leave me. I really tried to be perfect so he doesnt get annoyed, but im dumb and i couldnt do it. 

So i just want to write a letter to ask everything and maybe communicate about any mistrust or issues.

Thought here would be the best place to ask other people with bpd on their opinion if they were ever handed a note like that, maybe give me tips, tell me if it is triggering or such.
