Numb, emotional and distant bf after miscarriage

Shay
I recently went through a miscarriage on May 29th, my boyfriend and I were being intimate when I started to bleed and rushed to the hospital to find out we weren't going to become parents. Lately I have been feeling emotional, angry  everything you feel when you lose someone you wanted soooo bad. My boyfriend has been distant and not really understanding of what I'm going through. He asks me "am I okay" but totally shuts down whenever I want to go in dept about it and doesn't want to talk about it at all. Before he was very excited about the baby and now he pours himself into work. I still go through pains and bleeding I just don't know what I am to do. I lost my baby I think I'm losing my boyfriend too.
