First of all, you did the right thing. When this happens, you don't need to compromise, let alone give him hope of getting back together. This is actually quite good. You can also talk openly with him, and of course you can try to talk on the phone to make him clear his position. If not, you can cut off all contact with him directly and refuse him more clearly until he ignores you. I hope you can solve your problem as soon as possible.
