Yes, my ExH let me down badly throughout both of my pregnancies, the labours and coping with newborns.
Completely unsupported throughout labour with DS1. We had to stop at the off licence on the way to the hospital as it was about 9pm and he was cross because the "pubs will probably be shut by the time you've had it". He was right....that was on the Friday night (having already been in labour for 24 hours) and I finally had an emergency C-section on the Saturday afternoon. He spent most of the labour moaning that he was bored and tired, and was utterly irritated by me and the difficulties I was having. Sigh. Seems unbelievable remembering it.....I wish I was joking!
(I was very ill after the birth of my first son (the shock of having an emergency cesarean, then a bad wound infection, mastitis and pnd) and he carried on going out, drinking, being abusive, telling me he "just wants to have a bit of fun, for fuck sake.....")
Labour/birth of my second DS was no better. Unsupported again... Bored, fed up, tired, irritated, hungry etc. I was delighted to manage an assisted delivery (episiotomy and ventouse) after the previous c-section, he was unimpressed. I was allowed home the following day, he went out that night and didn't come home til 6am.
Yes, it further changed the way I felt about him, and no, I've never forgiven him. It's one of the biggest regrets of my life, that I did something so precious with such an arse. It still makes me want to cry :(
That was a lot longer than I meant it to be, and it's still only about a tenth of the story.
