People keeping filling his head about how his life is going to change? No offence, but he's hardly a teenager about to have his adult life and freedom stripped away and miss out on his party years is he? He is late thirties isn't he? Surely being asked to grow up and co-parent and share responsibility for a child he made at nearly 40 isn't too much to ask? You're the young one - you've got much more right to be scared I'd have thought!!!! He might be less selfish than your ex - but he still sounds selfish - sorry.
He's making his thoughts about the importance of the antenatal classes and sharing his birthday with you crystal clear. I hope he reconsiders about the sailing I really do. I can see the justifications for the other stuff though would still question the timing.
I don't think I've ever 'stopped' my DH from doing anything - I've never had to - he's imposed his own travel ban with work for the last two months of pregnancy and if he wants to go and do something on his own, fishing etc - it doesn't bother me at all - he just asks before making plans and makes sure he is in mobile range (reception is bad up here). It's a common courtesy. You don't seem to be an equal partner in this hon.
Sorry and btw feel free to ignore all of the above xxxx
I should stress that I'm not a high maintenance primadonna expecting your DH to perform superhuman feats of caring. Ads always jokes that I'm low maintenance and he'd like to see my high maintenance side in labour (am sure he will).
I'm just very wary of men that talk the talk but can't match their charming words with actions and end up repeatedly letting their ladies down and making the lady feel responsible / to blame or worse unreasonable for expecting them to support them through major stuff like errr, labour and pregnancy (but that's probably my ex issues coming to the fore!!!!) xx
