my hN insists he is very unhappy where he is and will be on his own soon-liar?

For all of you who know the inner workings of a narc, and I who am learning more and more, please remind me, every word out of his mouth is an utter lie. This morning he came here to finish the yard, and to make sure i used his account to pay the mortgage, as he pays all the bills here. He was cranky and rude, and said I thought you would have done it already, got snotty so I said whats your problem, dont talk to me that way, why are you so moody? His response was, it has nothing to do with you, sorry i was being such a jerk, but having more and more problems over there. She has been fighting with me for two days now and I cant take much more of it. I said, well, to be honest, if it were that bad, you wouldnt still be there, he said trust me, it will definately be soon, i have to get out. the fighting is out of control, but i think he likes the fighting, i really do. its the whole push and pull over there, she fights with him then begs him not to leave her. last week he told me she says I know youre going to leave me, im gonna come home from work and you will be gone one day, last week I asked what do you say to that......he said, i say nothing and walk away, i asked the same question today, his answer was, i say i wouldnt do that, stop worrying, he said but in my mind i say, cant wait for that day....and he laughed, so i called him on that lie, and he said, sometimes i dont say a word, but this week i felt like i had to say something, and i figured saying i wont do that stop worrying, she would stop nagging me. lies, lies and more lies. I dont believe for one minute its that bad over there and if it is, he obviously loves the drama. he wouldnt tell me what they were fighting about, but i bet its about his lies, lies, and more lies, maybe the whore is catching on, maybe she realizes she didnt win the prize, and hes not at all what he was like when they were sneaking around together for over two years, guess the honeymoon has to end with everyone at somepoint............what do you think?
