Journo, 30+ gsoh, ns seeks masochist to share laughs and late nights

I have been single for a long time. Too long.
I often question why, since I have had long term relationships before.
Clearly I have many issues.
Anger, selfishness, a sometimes obnoxious often narcissistic personality, a talent for fibbing, shallowness, a sense of superiority, rudeness and an almost tourettes-like propensity for swearing.
But enough of my good points.
I remember when my last serious girlfriend left me. We owned a house together, had moved a long way from home together and both worked for big newspapers.
Unfortunately she worked in advertising and I worked in news.
Her switchboard closed down at 5.30pm. Our subs started working then and calls and queries would come in thick and fast and continued well after the time I arrived home. Usually at 8.30pm.
When I worked late, late on Friday and was back in the office for a 14 hour day on Saturday she was often surprised when I wanted to do fuck all on Sunday except chill out and watch some TV.
Her complaint was that she was bored all day Saturday because I wasn't there.
My attitude. At least you weren't fucking working.
This bullshit continued for a time until one Tuesday an ominous text appeared - "We need to talk."
Oh fuck, here we go.
It wasn't a surprise she left and after some tears and shouting, that, as they say, was that.
Four years of my life down the shitter.
I look back now and wonder, however, was my work utimately to blame or did I work harder to get out of the relationship?
Who knows. All I know is that it was a period of my life that I was deeply unhappy, in a job I hated, with a girlfriend who didn't make any effort to understand what I did for a living.
She's married now. Good for her. I hope she's fat.
So why am I still single.
I think it's because of nights like these.
Nights where I come home utterly despondent and depressed. Fucked off with my shitty life and my shitty job.
Nights where I finally realise that no matter what I do and how hard I try, management don't care about what we do.
Nights when I think that twenty years in this game have been for nothing.
Nights when I realise that most people see me as the ranty old man crapping on about the past.
Nights when all the shit I have waded through starts catching up and the darkness starts to get harder to suppress.
Why would I want to share all that with anyone I actually liked?

ps Did I mention I like animals?
