Dealing with miscarriage

I found out I was pregnant on New Year's eve. It was completely unplanned and unexpected. My SO and I were so excited. However, I ended up miscarrying at 7 weeks. I am not taking it well at all. SO shows no emotion and doesn't care to talk about it. When he does, he just agrees with whatever I have to say. He is a man, and I know they show no Emotion at all. We do not want to try for another, as we would like to get married and have a stable life together. Not exactly sure how I should handle this..
