DB not showing That he cares about mc

Nae
sou we found put yesterday that my hcg levels went from 109 to 22 in 48 hours. Dr said I am going to misscarry. my DB hasn't shown much affection two rdr me sense the bleeding first started about 4 days ago... I feel like he is blaming me for losing the baby. he won't hug or kiss me now and we r fighting. I feel like I'm dealing with this alone.
