I am very sorry for the loss of your little baby Imani. I too have lost a child and so I know your pain. Don't place expectations on yourself as to how you 'should' feel. You can only just let yourself go day by day. It is just over two years since I lost my boy and I still have bad days. There is no timeline to grief so please don't pressure yourself because you think you should have moved on by now.
I highly suggest having a birth debrief. I did, and it helped me to deal with those images which were imprinted in my mind. It is such a painful (not physically but emotionally) experience so don't think that you have to just deal with it and move on without reaching out for help.
About your husband, men greive differently. I found my DH just wanted to keep busy and move on with life. It does catch up with them as it is only now that my DH will admit how grief stricken he is and now it is like dealing with Harry's death all over again.
There is a wonderful thread called parenting after loss which you are welcome to join. Hopefully you will find some comfort in speaking to other women like you.
Take care and be gentle on yourself.
Spring
