Miscarriage ruining relationship

Ever since our miscarriage it seems as though my husband and I are fighting more and, generally speaking, are not as close or intimate as we were before. He even spent a few nights at a friends house and I don't know if I want him back. I don't know if this is all grief related or if having a child together just really put everything into perspective and now we see each other differently. Anyone else go through the same or similar?
