Hubby and my miscarriage

I miscarried in December i feel like my man didn't really care as much as i did ..yes i know it wasn't a full grown baby yet but still ..I conceived a baby ! HIS baby at that ... He has 2 kids already from his ex and the other day just to see what he would say i told him he has 3kids , 1 in heaven & 2 here .. He looked at me like im nutts ..as if our baby didn't count because we lost him or her so early ... All he said when i found out i was misscarying was Atleast we know it can happen (we had been trying for 4yrs) .. He really upset me :( .. Why are men so cruel.
