I was also fortunate to have a supportive partner who gave me as much support as he could while also working through his own grief. Without his support I know that my grieving would have longer and harder to deal with The spouse or partner is often forgotten when it comes to seeking support. In some cases it is because people don't think they need the support or because they do not ask for it. I can see how it would be hard for the husband/partner to ask their wife for support when they know she is going through both an emotional and physical loss.
I know that once I shared with others that I / we had a miscarriage, how many others had a similar story or knew of someone who had been through the same thing, Since the loss I know a few people that have experienced a miscarriage and I have offered them my support in what ever aspect they need. The best support I think I can offer another is an ear to listen, a shoulder to cry on and the knowledge that I understand how they may be feeling.
