Just told him I hate him

[coocoocachew]

We've been together 8 years and have just had a baby. He makes me sad everyday, happy sometimes, and I know I irritate him. I can't describe what is wrong with us, but I think about leaving him a lot. He's cold to my parents, never compliments me or makes me feel good. I was originally attracted to him as he is aloof and we had a lot of banter - always teasing each other. Now it just feels like he doesn't like me and he's cold and distant all the time. I don't know what to do

Tell him you want to end things?

I told him I don't want to be with him anymore. He confuses me so much and makes me feel like it's me that's crazy and unreasonable. I don't think I am but maybe I have a blind spot. He's a lot smarter than me and I worry that he controls me with his intelligence (iyswim). I'm so confused

Have you asked him what he's thinking about you? It's easy to be intimidated by people who have a wide vocabulary. However, this doesn't mean that these people are more intelligent, almost certainly not more emotionally intelligent, anyway.

Is he arrogant too? If so, I know the type fairly well and believe me, it isn't you its them.
They get a twisted, perverse sense of superiority from being 'right', about everything. It feeds their little egos to put you down in order to put themselves up, way up, so that they're towering (they think) over you.
Often obsessive about imparting little gems of general knowledge to their public, (that's you, incidentally), they can be tedious people to be around and maybe, he's feeling that your feeling boredom with him so he has to 'win', by asserting his superiority through behaving disdainfully.
If I'm right and these characteristics fit, there's no way you'll live a happy life with someone like him and you deserve to be happy.
Everyone does.
