How do I delete messages on my Ebay overview page?? When will it disappear?

[hlavendale]

I received a message about my listings.  I responded, he responded back, and now if I respond he will answer back again and leave me with "unanswered messages " on my seller overview page.  How can I delete these unwanted messages .  I don't want to respond because he is offensive and the back and forth emailing is not what I want.  He attached me, I don't want to respond.  I just want to delete his messages.  HELP.  How do I clear my message overview page of saying I have unanswered messages.  When will they drop off

Deleted messages go to your Trash bin, and ebay automatically removes them after a time (not sure if after 60 days or longer).
