<human>: So today someone i work with royally pissed me off. 
It came up in conversation that i had broke  up with my girlfriend of 11 months and i gave them some old generic reason of it just not working anymore (Although it was far more complex than that). Now usually thats the end of the conversation but  of course some smart arse decides to start digging and poking fun about the situation. Making remarks about me being an arsehole for ending things due to my given reason and calling me a smug bastard. Things of this nature. Now usually i brush off his assholary with some witty remark about something and we laugh it off, however this time i couldn't because the truth is (and of course i haven't told him this) the real reason for my relationship ending was for many unfortunate and more serious reasons, to avoid being specific there were clashes with life plans, mental health issues and other conflicts that lead to an agreement that although we would not continue as a serious relationship i would still be there to support my now ex girlfriend through her tough times because its nothing personal it was just the stress and pressure her issues were putting on us. 
That being said i didn't want to tell the affore mentioned prize prick this because he would probably find ways to make jokes about it as he has been known to do. Instead ive had to take it on the chin and stay quiet. However its resulted in me coming home from work in a foul mood. 
I guess this rambling is just me getting things off my chest so i can cheer up and carry on with getting used to the fact that im single again yet happy with life and the fact ive managed to salvage a friendship out of a failed relationship. 

Again i apologise for the lack of coherence in this and possible bad spelling. Im just getting things off my chest.

Give me the gist of the text in a nutshell
<bot>: Asshole at work makes jokes about my relationship ending. He doesn't know the full story. I'm mad bro.
