Long term poster here but name change in case anyone in rl recognises me.
I can honestly say when I met dh (not so) I would never have said he was anything other than thoughtful,polite,respectful and kind.
20 years down the line I've had enough and emotionally checked out years ago.
We had a big blip and dh left for a few months. I should have gone with my gut then and said no to a reconciliation but I still wanted that happy family and look at all the years hard work into our home and life.
Now I see they are material things and the more I look back at memorable fall outs they were all over his behaviour or selfishness or attitude or arrogance.
His lack of empathy for anyone is at its worst now and he's on self destruct mode but as ever it's always someone else's fault 
I know I have no feeling or attachment to the person he was or I was or the house we've created as I feel absolutely nothing towards it or him.
I just feel anger and resentment towards him,his behaviour and his attitude that when I call him out on it I'm blanked for days and Hel do nothing with or at home to help and create the worst bad feeling ever. It's his vicious circle of control. Just when I get to the point where I've had enough and tell him so Hel stroll in and make an effort with the dc and chat and do stuff around the house.
He's currently hanging washing out and cooking for the dc. He hasn't done either of these out of spite for over a week now.
The more he behaves like it the more it now makes me want shot of him. I used to hate it and try constantly to talk to him only to be yelled at and batted away like a pain in his ass.
Not anymore. He earns a a lot more than me yet the bills are still split 50 50 as he has to control his own money which he blows every month on things just for himself.
Think hundreds on body art gaming stuff and alcohol.
It's like having a stroppy arrogant teenager in the house. I look at him and cringe.
He is a narcissist. His behaviour is to an extreme to gain control of any situation he needs to gain from.
He isn't in any way normal nor is his lack of ability to put others first.
Everything's done out of a gain for himself or spite.
He also has no morals.
I feel so much better I've put that in writing.
