How long should you ignore someone to get your point across?

I stopped talking to a guy because I found out he started hooking up with a slut when we were attempting to fix things between us when she was originally the problem. He started texting and calling to ask why I was ignoring but I just keep not answering he asked to have a talk after about a week and a half but I haven't answered that one either how long should I keep this up for? never talk to him again or give in and listen to what he has to say which are probably lies.
