Wow dobby thanks for your post! Its nice to know that some men change for the better...AND that he is not the only mummys boy! She's a nice woman, but if its not him phoning her to give her running commentary on what he's done that day even to the point of his bowel movement, then its her phoning him for any reason she can think of! It drives me bat shit crazy, even if we come out from an appointment somewhere, we get in the car, and the first thing he does is dial 'mums mob' on the car phone to fill her in!
My mum and her partner turned up with food, chocolate, and to help clean the place up...he simply got up from sleeping on the sofa and went out in his car...awaiting his return from what is obviously mummys...i dare say he's had his head filled with some sort of shit about how I'm not doing what I'm supposed to be doing, and how amazing he is compared to me (I feel your pain)
Thing is, he has kids from his first ever relationship of 13 years, and he knows the drill...difference is, this time round he's here for the whole gritty experience (he was always away severing for months at a time the first time round)
In his words he can't wait to have a second chance at being a proper dad, which I'm certain he will be brilliant as he is deep down a loving caring man, but his attitude towards me really concerns me, because if that doesn't change then he won't be around 'all' the time to be that 'full time dad' because he certainly won't be living with me. Its just so hard to draw a line and stand by it when you're clouded by how much you love someone and 'really want' it to work. But as I have said, lo cant grow up thinking that's how to speak to and treat a woman.
Unfortunately its very clear why he thinks its acceptable, he talks to his mum like shit too and she just takes it, never corrects him or anything, just puts up with it...and there is NO WAY IN HELL that I would tolerate such an attitude from my future son. Children live what they learn, and sadly he's learnt his behaviour from mummy! 
Don't get me wrong, my dh has moments that remind me why I love him, and most days he does the majority of the housework (I do what i can depending on my level of pain)
Its just when he has these phases, its always some majorly blown out song and dance that takes days to overcome, by song and dance I mean taking back my wedding ring, saying it's over etc etc.....of course these events never end in him taking any responsibility for the way things are between us, its ALWAYS my fault, including the way he speaks to me, that's usually my fault too apparently 
Brilliant that your dh is doing his bit though hun, he sounds great! 37 weeks too! WOW the tww (three week wait) is here! Bring on the symptom spotting
