Oh I understand you OP. The 'is this really that bad? Is this actual emotional abuse? I can handle it so surely it isn't so bad, and there are so many others out there worse off' - all the above and more. The death by 1000 paper cuts is spot on. Emotional abuse doesn't have to be big things. Long term thoughtlessness (at best! At worst is downright hostile) behaviour can kill your spirit. You sound like you're in the same boat as I am.
I kept trying to make things better with mine, because we have children. We rowed constantly, he was mean, moody, random hostility, lacking in empathy, pride, never laughed at my jokes and never engaged with my conversations. Once started leaving a voice note for his mum as I was half way through a sentence. Would call me boring if I called him out on why he didn't listen to me. Would pick a fight and then ask innocently why I was so angry. So much more that I couldn't put a finger on but sounded silly if I complained about them. I would bend over backwards to work out 'techniques' that could help us avoid the triggers... code words or signs to back off, but nothing worked. And after each row he would put in so much effort that I thought 'maybe this time' it'll be better.
In the beginning I could heal after each row, have hope, but soon the healing became impossible. I think the beginning of the end was when we hugged and instead of feeling connected and glad, I realised I was just staring into space, thinking "I wonder how long until the next row". I had disconnected.
The 'straw' for me though was he did nothing for my birthday. Didn't even tell the kids it was 'mummy's birthday'. Just had his cereal, left it in the sink for me to wash up, and left the house. And then shortly after I tried to talk to him about a friend coming to visit, someone who had been supportive during my pregnancy with our first child. He was so uninterested and I realised I was so lonely. Had been low level depressed for so long that this was my normal. I saw a video that night on Facebook about emotional connection and how women often find this lacking in their relationships, and all the comments in this video were of women saying "yeah, I've given up trying to connect, I just chat with my friends instead' and I thought "fuck that, I'm not going to spend until death do us part talking to myself in a vacuum of gloom" and so I have requested a separation (yet to be implemented but that's another story.)
I feel so much happier that I've made a decision and will be showing the children that you don't have to put up with something just because. I read something along the lines of "I'd prefer to adapt to living a more difficult life without this negativity, to adapting my boundaries to learn to live with it." That resonates with me.
To be honest though he really doesn't get it. Veers from "you're leaving me because you want to pursue other interests" to "I don't know why you're leaving" to "I'm sorry I wasn't there for you" and "it's not too bad at the moment, we're not arguing, why can't we just give it another go". He just doesn't get it and I'm so tired of the energy being sucked out of me to keep explaining it to him. Not sure what the future will hold - he's not a bad man in many ways, just not a good one to me and clearly doesn't love me in the way I would want to be loved.
