I had my LL last year a few days before the first lockdown, he was three weeks early and we had to go back in to hospital the day after we got home because he'd lost too much weight, he was severely jaundiced and was taken in to NICU that day, he was three days old. My OH has two children from a previous relationship and he has them for a few days every week. The day my LL went in to NICU he told me he was taking his children the next day for their scheduled visit. I have no family near where I live and the first lockdown had just been announced so I was relying on my OH to support me. He spent the next day complaining to me about who would look after his children overnight because I needed him with me to help so I could get some sleep in-between expressing, then the next evening after when I asked when he was coming his reply was "do I have to?". He doesn't drive so he couldn't come pick me up when we were fit to go because he didn't want to take his children to the hospital and didn't want to ask anyone to look them because of the Covid situation, I had to get my brother to drive to our place to pick up the car seat then to the hospital to take me home, he lives an hour away from me.
We've argued about this on and off since then, I don't think he should have taken his children and he abandoned me in hospital to deal with a sick newborn. He says that he has responsibilities, his children come first and that I should understand that now that I'm a Mum. Am I being unreasonable or is he being an arsehole.
