Will you block your first ex boyfriend?

My first ex boyfriend was really good. He was not at all like other exes. He treated me really well and was kind and we dated for 2-3 years but we ended coz I broke up with him as I couldn't feel the spark anymore.
Since then it has been more than 2 years and we are friends not too close but casual friends and I have dated other people after him.

Now my current boyfriend wants me to completely cutoff my ex but I don't really want to do this because he is one of the very few good and kind people I know. I have tried to explain my boyfriend that everything is over b/w us and we are just casual friends now.
What should I do?
