DragonCookie, Im sure that your DH has concerns about your PND too but as it effects women for many different reasons there is no guarantee that you will even have it again, so I don't think that would be his main concern.
perhaps he was just expecting it to happen like you, and thinks if he just keeps putting it out of his mind ....it will happen and you won't have to be one of those people that TRY to have a baby, especially after having an oopsy baby first....same as us.....
( No offense to those trying for a baby, I am too but some people don't like to be 'branded' as someone that HAD to TRY )

my DH doesn't want to ""try"..... He basically avoids me if I say I'm ovulating, even though he was the one that suggested it was time to have another baby in April. It certainly doesn't help that I took him seriously and put my heart into it straight away,( especially after my miscarriage) whilst he just expected that his super sperm would knock me up straight away, I think it bothers them more than we realize but they don't want to talk or plan or "TRY" for a baby, but they will have sex, when it suits them. I get where you are coming from and I understand your frustration with waiting months.....

I don't have any advice on how to deal with DHs attitude as I'm certainly in the same boat. Ive tried talking about how much I want this, especially after the miscarriage, and how we actually have to have sex at a certain time each month. That DS was not simply a fluke but rather good timing... DTD.

I hope that in the next few days you can resolve things, and try to work together towards a baby together as YAS said in her post, it's a joint effort and when they aren't in it with you, you can't do it by yourself, especially emotionally
