Wife carries on communicating with former best friend

DEAR ABBY: My best friend of more than 10 years, “Ian,” ghosted me! We used to talk about everything — wives, children, jobs. We spent hours together and helped each other sort out our problems. He knew more about me than my wife. With no explanation, he stopped responding to texts and messages and is ignoring my calls. I have come to terms with this and deleted him from my social media and social circles. It’s been two years now.
