They could’ve been proactive and told them why they’re not going to be texting anymore, instead of literally ghosting them and then saying that’s not what they did. 

Regardless of reasons, completely cutting communications with someone out of the blue is “ghosting” nowadays. It may have been completely justified, but that doesn’t make it something different.

It’s only ghosting I think if he didn’t reply afterwards when she said “so you ghosted me?”
