Newborn and lack of help

Hi,

So basically, I have a newborn beautiful baby that was born two months premature. He is now two months old but was only due a few days ago.

My partner works but I will be working from next month again.

When we went into this, he said we would share night feeds. However, since having our boy it's been all me. I am DRAINED. I have zero help at all during the night. Nothing. He sleeps in a separate room so he doesn't have to hear the crying etc and justifies not helping with 'i have to go to work'.

Am I expecting too much for wanting some help in the night?
