Personally, I feel my husband is completely wrong and his response was to be nasty and do me a great deal of harm.
For example, literally days after I got home from the hospital with a tiny newborn who wouldn’t be put down (day or night), recovering from a hugely traumatic emergency section, trying to establish breastfeeding… did he help or support me in any way?
No. He did not. He decided that he was angry that he wasn’t getting my attention or the bits of babycare he felt were full of sufficient glory. Before the baby was 5 days old he was angry at me for not expressing so he could bottle feed if he felt like it. He wasn’t getting his own way so he wouldn’t help me with anything at all. Wouldn’t do the boring shit like holding the baby while he slept (so I could spend any time not in physical contact with him).
Before the baby was a week old, he was badgering me for sex and wouldn’t take no for an answer. He expected me to just look after the baby while he had sex with me.
Even where he did do something useful like cook, he insisted that I sat in the kitchen and supervised/instructed him in how to make the things I would have been cooking that he wanted to eat. The first weekend of DS’s life, his father was livid with me because I refused to get up (after an entirely sleepless night) and hold/feed the baby in the kitchen while talking him through how to make pancakes.
And many other things. Ultimately there was financial abuse, destroying my mental health, all sorts of things. So no, in my particular situation I don’t think I should have given my husband more attention. I think I should have left him before I even had the baby!
