Can't Win For Losing

So I get to work today and discover that the job responsibilities list is still not updated since the new six week schedule began yesterday. I normally just take the initiative, but I was told that the manager would take care of it. He didn't.

Stick Figure(3:20:47 PM): how come you haven't updated the work schedule...i figured you would do it last night
Camlaw(3:21:07 PM): I have been told to mind my own business
Stick Figure(3:21:33 PM): The Menace or Ms. S
Camlaw(3:22:45 PM): The Menace...kind of...I was told...I will take care of it....Like leave it alone
Camlaw(3:25:32 PM): Do me a favor and ask Joe what he wants to cover... I will update the d@mn thing
Stick Figure(3:31:24 PM): Joe(15:24:59): well i'll just do Chatterbox's part then...at least till he updates it right
Camlaw(3:36:32 PM): OK...I updated it

Next thing I know I receive an instant message from Joe.

Joe(3:38:14 PM): why cant you just ask me? this is a job so get over your personal stuffs to get this job done.
Camlaw(3:39:27 PM): The last time I spoke to you, you threatened my job, so I am just trying to respect your wishes and leave you alone.
Joe(3:39:54 PM): last time you spoke to me you did the same....
Joe(3:40:06 PM): but this is a job so deal accordingly

I began to respond to this with long ass rant. I said that I cannot win. That no matter what I do he treats me with such hostility. That I've tried being nice, hiding out, giving him space and he still manages to chastise me. But instead I just sent this:

Camlaw(3:47:24 PM): the schedule is updated
Joe(3:47:58 PM): the schedule?
Camlaw(3:48:14 PM): the responsibility schedule.
Joe(3:48:28 PM): job duties...oh ok
Camlaw(3:50:47 PM): Just for the record. My intention was never to threaten your job.
Joe(3:51:26 PM): intentional or not, it was.
Camlaw(3:52:49 PM): Then I apologize.
Joe(3:55:26 PM): i never threatend your job...i just said dont use co communications for our personal issues ....because this is not company issues
Joe(3:55:59 PM): so all is done now...so no more talkin bout this on co communications
Camlaw(3:57:11 PM): ok

I am assuming that he means that I threatened his job by using all those cuss words in a company email even though the words were spelled with symbols. But he did threaten me, in all capital letters no less. He threaten to report me to management...not politely ask me to no longer send him personal emails at work. Every one I shared his email with took it as a threat. I didn't feel like arguing the point with him though. He still thinks he did no wrong. It's all my problem, my issue and he is just the innocent bystander.

I plan to leave work a few minutes early to avoid walking with him to the parkinglot. He is just so fucking cavalier and content with the ways things are between us. I can't fucking stand it!
