I think the guy has moved on after she didn't set up a coffee meet.He took that as disinterest to take this relationship forward,more than a phone rant buddy thing on her part.It does look like he had genuine interest in her.She mentioned he said so multiple times.It started prepandamic, so my guess is now been 2-3 years.I mean it does look like a phone pal relationship, as they chatted for hours 13 times.Guy was hinting her to take it forward though.They chatted hours before,and it sounds like all chats except the last one went well.If guy was arrogant since the beginning, then the question arises why OP would continue to talk for years.The guy went bollocks as he assumed OP was just using him for phone rant.Seriously,if you ask me,tell me if this relationship was something else other than a phone rant,which he mentioned many times he was not interested. He may be plodding along in the hopes of meeting for real which didn't happen anyways.That is when he stopped responding to calls.Op should have understood those cues.Like I said before miscommunication seems to be culprit here.
