My abusive partner had this trait. I later learned he has Narcissistic Personality Disorder. He has no empathy even though he faked having it for the first year or two, had child then he let his true colours show.
For example he would leave me with our toddler and me curled up on the bathroom floor with a severe flu, too unwell to hold my own head up to throw up, or have enough strength to hold a glass of water up to my mouth to stay hydrated.
I was curled up with two duvets and laying with my back against the radiator but i was still freezing. I had extremely violent rigors - whole body shaking with fever that was clearly visible to him, as was my vomiting, and general paleness, sweaty skin, and looking like death. He still said I was faking it, and just trying to ruin his day at spoil his plans and he’s not falling for it! He would never listen to reason and in his mind was NEVER wrong. He would judge me and project his nasty manipulative behaviours and thoughts onto me as if i was capable of what he was. He wasn’t capable of being reasoned with, he would not listen and would literally walk away or leave the house when i tried to get my feelings and needs across to him, he was incapable of seeing genuineness. He would only want to fulfil his own selfish needs and twisted agendas. With no conscience or awareness of the hurt and destruction his moods, temper, rages, tiarades, vengeance and overall horrendous behaviour was having on me and our child.
He was giving me verbal abuse and evil hateful glare as he walked out the house. I truly was not able to take care of our child. He left me alone with our child the entire day and evening from very early in the morning just to play golf, because it’s more important to him. He was good at it so he got his ego stroked through it.
After he left our house, I had to crawl to the landline house phone to call my Dad to come home from his work to get my daughter. Abusive partner snarled at me with hate and contempt, he had to give me one last hateful evil glare as he closed the door. More often than not he never believed me or had any sympathy or empathy, yet he would expect everyone to fall in line and run around playing nurse maid if he was sick.
I started having real chronic health problems and later diagnosed with multiple serious conditions that have left me disabled and will shorten my life by half. He never got any better, only worse. He wasn’t even there for our child when they were 12 and hospitalised and had hallucinations, delirious, near death with sepsis from a kidney infection.
This is not even the tip of the iceberg of the horrors and controlling coercive verbal and emotional abuse he has put me through.
Hindsight is 2020. All i can say is this lack of empathy and respect is a MAJOR red flag🚩. He will not change. Don’t live on the hope things will get better. It doesn’t. Run. Don’t have a child with this man. It’s not a quality you want in a partner or Father.
