Messaging someone and saying , " I don't want to be friends " seems rather pointless to me.
Just carry out the action of not responding if that's the way you feel.
You seem as if you don't know what to do about this entire thing.
I think you should leave his response and not click ignore.
Give yourself time to think and then accept his request.
You can at least hear what he has to say if it means that much to you.
But definitely do not make him interfere with your life because it seems to be going great
