Does it work?

I went on one date with a man. We had sex. I told him we were not compatible.I have blocked him on the dating site. Since then, he has sent me about 15 messages. He knows my phone number.

I have ignored him for 13 or so of those messages. I finally sent him 2 messages telling him I was not interested.

Is it better to continue to ignore him?

What would you do?
