Look at this as an opportunity to remember why you started No Contact in the first place..... he's with someone else, he doesn't respond back to your emails.... so let those two things be the reminder to not respond to any of his emails.
Do you have Outlook at work for email?
Hi:
Thank you both for your replies.
Yes, I remember that he was two-timing you, that's why I said I'm not sure why you'd want to be friends with him even down the road.
I would email him with the request for no contact.
