Fair point Rindercella. Your advice was tempered and didn't advocate confrontation.
I didn't cite the example of the baby wipes incident as any kind of proof the OP was controlling or abusive, or useless. My intention was to suggest he may not have been doing as much of the baby care as he claimed if he hadn't lined up the supplies first. I also remarked in the 'wipes' post that he used this incident to portray himself as Mr Nice Guy Doing His Fair Share and getting wipes thrown at him for his pains, in contrast to his wife, who comes across in his description of the incident as unhinged. The wipes incident came across to me as an exercise in case-building, and despite his protestations, there was a lot of 'poor me' in his account of the incident.
Regarding my observations of my ex's 'help'; they are no more or no less relevant to the thread than any other contributors' observations that were based on their own personal experiences of living through the post natal period. Many have described living through PND, either suffering from it themselves, or living in a home where a mum had it. While I didn't have PND, I have observed well-intentioned efforts going awry, and felt occasionally that no help at all might be better than the kind of help/involvement I experienced. Some of it was pretty funny, but the joke wore thin at times too. The gist of my last paragraph was how annoying it was, and PND surely magnifies a lot of little irritations. The OP should not have described the wipes incident the way he did while at the same time claiming to have taken on board what so many posters had said about PND (clearly the reality of PND had not sunk in for him at all) and how it affects feelings and behaviour, and all the while claiming to have no anti-wife agenda.
LostBoy/LostDog has posted a few long posts after his OP that demonstrate a defensive attitude, and no acknowledgment of suggestions that PND may be at the bottom of his wife's changed demeanour or insights into PND that he may have gleaned from his own research. There has been no effort to respond to pertinent questions about the amount of support his wife has in RL -- a lot of posters have expressed concern about this aspect of her life, and have suggested this might in fact be a great way to be helpful to her, and he has made no comment about it. "I have never forced my will on my wife of daughter and would never overrule any of her descisions on the basis that I didnt agree." Directly contradicting yourself doesn't help either. There's no examination of his perspective here, nor is there even a clear idea of what he may have done and how it may have been experienced by his wife. If he's invested in the Relate counselling, and if he wants it to get somewhere, he needs to do better than that. "Yes 2010 of course I have tried talking to her and asking her if there is anything I could do to help That is one of the reasons I am not staying at our flat at the moment because she asked me to move out for a while to give her space." That sounds really clueless. Maybe it's the best he could do, but the mental image I get here is two ships passing in the night.
I have lived with someone who had undiagnosed depression for many years (he didn't think he had a problem, everything was my fault) it didn't happen suddenly as PND tends to, but rather it was part of the wallpaper of the relationship, maybe right from the start, I don't know it's hard, and at this stage pointless, to untangle the puzzle. Depression was only one part of it; there were other issues too. It colours everything in a relationship. The level of hostility that was often directed at me was breathtaking. There were long stretches where I felt I could not win for losing. LostDog is no doubt feeling bewildered by the turn of events, and hurt too. It's hard to sort out what's a relationship issue and what's the illness, but a lot of people have tried on this thread to point LostBoy/Dog in the right direction. So why does he thank posters who have "stuck up for me"? Some posters have asked early in the thread what the Relate counsellor may have said about the PND, if the issue has been raised in the sessions. It seems pointless to me to have someone who has PND going to Relate in the first place. A case of putting the cart before the horse, imo.
