<human>: I gave birth just under two months ago, she's been a very difficult newborn as she suffers with reflux so 90% of the time she spends awake she, unfortunately, spends screaming.

He's a fantastic dad, goes above and beyond for both me and our baby, I struggled immensely at first, having a depressive episode myself and even trying to leave them both as I couldn't handle the stress of being a new mother. He took on both roles the whole first month solidly as I just cried as much as our baby did and basically rejected her.  To be honest I rejected the both of them.  He was trying so desperately to help me get better he seems to have suffered emotionally himself.

I feel 80% better in myself, I've taken to the baby and I'm growing in confidence with her everyday but my boyfriend is not himself.  He's sad a lot, always looks deep in thought, won't let the baby go to anyone else as he feels he's the only one who knows how to look after her and he's just really, really sad.  He says he feels weird and just wants things to go back to "normal" but I don't know what he thinks normal is. 

I try to talk to him and get him to open up about how he's feeling but he just doesn't have it. I do more with the baby and let him relax and have long sleeps at night, try and be positive about everything, tell him I love him a lot and how grateful I am that I have him, what a great dad he is etc, but nothing seems to make him feel genuinely happy like he used to be.

It's obvious my actions in the beginning have completely messed with his head as I left him to do everything for the baby and was just a vile bitch for over a month but he won't admit it.  Now I am feeling back to my old self I don't know how to help him.  Is post natal depression in men even a thing or have I driven him into just utter depression?  How can I make it better?

Can you condense the text into three sentences or less?
<bot>: I rejected baby, boyfriend did everything for the baby, I feel better, boyfriend seems depressed.  How can I make it better?
