Inside his head

Last night I bumped into my exN. I’ve gone complete NC since an ugly fight we had last week while we were trying the ‘friends’ thing. So he asks me why I don’t want to see or speak to him anymore. I was on my way home after drinks with friends and was rather tipsy so my guard was down… I said I can’t hang around him anymore because I still have feelings for him while I know he feels nothing for me. And this is how the conversation went (I wrote it down when I got home so I could remember it all!):

Him: Well I don’t feel anything for anyone, including myself.
I don't feel anything for my parents, my sister, the dead
dog I buried today (his mom's beloved dog died and she is
devastated).
Me: Why did you bother hooking up with me in the first place
if you know you don't feel anything for anyone?
Him: I thought and hoped I changed, I thought it would be
different, that I would be different this time.
Me: Did you EVER feel anything for me?
Him: Yes I did feel something. All the things I said to you
were true (contradicting, I think he felt something but
didn't understand what it was).
Me: Then what a bitch it must’ve been when I became soft and
began to have the need to talk about feelings (during the
fight the previous week he accused me of becoming 'soft'
when we were together because I wanted to talk about
feelings). All your ex's must've been heartless then!
Him: Yes most of them were. I don’t know what’s wrong with
me, there's something wrong with my head, I don't know
what's going on. I know and am at peace that I'm going
to be alone the rest of my life and die alone.
Me: Humans are social creatures, how can you just be happy
with that?
Him: I’m not social. I have my own universe I live in. I
can't imagine why anyone would like me, what's there to
like about me. I don't even like myself.
Me: Am I supposed to feel sorry for you now?
Him: No but do you really never want to see me again? You are
my connection to the outside world, telling me what's
going on in your life and around town, the gossip.
Me: You won’t even miss me when I leave (I’m moving away next
year).
Him: I’ll miss our little get-togethers and the fun.
(Interesting how he won't miss me). If you change your
mind on spending time with me, I'll be here. Is there
anything I can do to change your mind, anything at all?
I guess there's nothing I can do...

And from there I basically just ended the conversation by saying that’s how I feel and he should respect it and leave me alone. I know one can never really believe what Ns say, and I never should've engaged in the conversation but I have a big mouth after a few drinks! This just was the first time ever that I felt he was honest to me. I’ve learnt his tone and body language when he says things just to get attention/sympathy or when he says things he thinks I want to hear. And last night was completely different, I sensed a bit of desperation. It felt like he was admitting trying to live through me because he can't 'live' himself. Just wanted to share it...
