first off, guy friend should not have continued to engage on the topic of YOU. nor should he have gone on at such length, and then repeated it ALL back to you nearly verbatim.
as it is - this was not a conversation in which YOU were involved....so it doesn't really matter what was said. but you are now making it a big deal as if YOU spoke to the ex. you too could have said, don't wanna hear it, thanks.
time to get back in your hula hoop, shake off his drama, and move on.
