Is my ex toying with me or am I paranoid?

Anonymous
So I've been talking to this guy for a while and he never sent me a Snapchat via the app just photo's via chat. He copped it as just being insecure after his dad damaged his face with glass but a couple of nights ago he sent me a voice message moaning and saying my name. He sounded exactly like my ex and I told him he sounded familiar. He then went ahead and deleted all the voice messages he had sent copping it again as being gross. I asked him to send one without him moaning or for us to call, he said we will but I don't know when that will be. So my friends decided to confront my ex who I hoped I would never hear from again, let alone speak of again and he quickly turned the conversation towards his own problems. How some old friends of his are harassing him about some book and accusing him of the same thing. My friend called it interesting that they would be accusing him of the same thing and he quickly went back to saying a girl called Ana is harassing him.
That he isn't pretending to be anyone, he and I should never speak again because it is for the best. Unless somehow some people can sound familiar to one another I think he's just denying it at this point while throwing his friends under the bus as a last resort to free himself out of a sticky situation.
