Hello, I feel disrespected by a coworker. Can you take a look at these models?

C: Coworker does not reply to 3 emails for 3 months on information I need to communicate to leadership.
T (old thought): He does not respect my need to get information to be successful.
F: Disrespected
A: Inquire why he is not responding. Decrease frequency of emails in response to his reply that he doesn’t have time to read emails. Harbor a grudge. Not continue to push for the information.
R: I do not respect my own need to get information to be successful.

C: Coworker does not reply to 3 emails for 3 months, impacting information I have available to communicate to leadership.
T (new thought): I will find out what I need to know regardless of what he thinks of me.
F: Empowered
A: Text him instead of emailing. Call him. Be direct in phone call. Let him know I need him to communicate since this is a workplace and I need information.
R: I find out what I need to know.

I do not appreciate at all how this coworker ignored me. I feel it is wrong and it’s hard for me to just pretend like I’m okay with it, but I feel pressured to do that since he is now in a powerful position. He even had the audacity to send me a long rambling email about how he hates email and has stopped using it. Ummm….maybe *you* are the problem (not me) if you insist on long boring explanatory emails like this – you could just reply with a simple sentence! Also, since when was email just optional because someone randomly got annoyed with it? I just can’t believe he is even still employed, much less high up in the org. He must treat people above him so much better as he was recently promoted to a high level position. These thoughts make me feel even more disrespected. It makes me feel the world is not fair at all.
