I can't say why he is always baiting her into conflict myself, but if it is
some unhappy experience in life, it still doesn't make it ok.  What has she
made up?  I would like to see these posts, because either I missed them or
my
emails really have not been getting delivered.   
I can't speak as to why she blocked you and continued to send you mail,
just
as I can't state why it is that Kevin keeps baiting her into conflict.  It
wouldn't be fair for me to assume anything here.
Once again, I would like to see these posts.
