coping

So My Boyfriend and I Had An Unexpected pregnancy. We were still very blessed and thrilled. I had a miscarriage around 4 and a half weeks. (Last Monday) he brought it up today that he feels sad and down. He told me he refuses to talk to anyone. I want to let it be and just wait for him to come to me. We are currently not moved in together right now since we are looking for our own home and told me when we find a home we can talk about it. Should I let it be until he tells me? What if he never tells me or thinks I don't care about his feelings ? Anyone else going through this or has gone through it? How did you guys cope ??
