For me, I no longer include ex's in my life. No point. They have nothing to contribute to my life and I have enough other friends. Plus, who ever you are dating probably will not like you still talking to an ex. Simply denie or ignore his request. You do not have to explain shit to him either!

If you really dont want nothing to do with him block him. That what I would do. He doesn't seem to respect your decision of not wanting to accept him as a friend. Only add him if you really want too tho dont do something you dont wanna do.
