My ex won't be freinds with me?

me and my ex decided that we aren't right for each other so we decided to breakup but we i asked him to be just freinds -knowing that he is freinds with all his exs and he to them normally - he refused and said "i don't want to be close freinds with you i don't want to be your freind and i don't want to talk to you but if you need any help i will be glad to help "
what the hell that suppose to mean , i don't want to lose him he is really a nice guy and i think that we work as best freind more than lovers
what should i do?
