How can I delete the chat history between me and my friend on HIS account?!?!?!?!!!!!!!(facebook)?

[Big blue eyes]

So, I have these conversations with my guy friend, and they are REALLY flirty and kinky.....sadly I'm not normally like that around people who aren't my friends, and I don't trust him that much....so I'm worried that he'll share the conversations with his friends and.....there's a high chance that he likes me--which means it'll be easy to hurt him to the point of spiting me with sharing my kinkiness........

I want to know if I can delete the hstory on my end and subsiquently delete the history on his end?? or can I unfriend him and subsiquently delete the histroy on both ends??? And if not......do you have any ways to make him think it is urgent for him to delete the history and so make him to with a high chance of success????????


PLEEEAAAASE HELP!! I'm really scared and don't mind the people at my school finding it but do mind people that I may work with in the future finding out and firing me/not taking me seriously.....I also don't want my crush to see this (I'm 14)
