Unable to show emotions after loss.

I had my second miscarriage unknown not too long ago. I thought it was my period just heavier and that my cramps were just getting bad again but it was a miscarriage. I told my partner the day I found out and that was also the day he got his son. As soon as I told him he wanted me to smile because I was at work which I understand. As soon as he gets his son though, I can't show how I feel about it at all. I can't cry, be mad. I woke up out my sleep and he blamed it saying his son was here and that's why I was acting the way I was. He went right back to sleep with his back turned against me while I cried myself to sleep. I don't even know what to do or how to feel.
