Blimey raggybaggy, if I was married to your dh our sex life wouldn't have gone off the boil because I was pregnant (which I am) but because I would want to strangle him with my bare hands!
I will say that I sometimes get very frustrated by having to be the one to do all the 'talking' on holiday or deciding where to go. I speak Spanish and we do (or should that be 'did'!) go on holiday to Spain quite frequently. I mitigate that by going to eat in touristy places where they have menus in English, so I don't have to translate the entire menu every time (verrrrrry frustrating) and by not trying to organise everyone's day for them but hand over the guidebook and let them work things out for themselves. I'm lucky that dh is pretty confident in foreign countries having lived and worked all over the world (apparently without ever learning any foreign languages, although he can understand Swedish pretty well) and will have a go even if that means saying 'tack' in Chile and 'gracias' in Sweden .
However, the other way I avoid it is just not going to places where only I speak the language. Next time he suggests Paris, why not suggest Amsterdam or Copenhagen?
I find the trying to get you to drink more completely unacceptable. There's a section in one of my pregnancy books about 'what to do if your friends are encouraging you to drink' and I thought 'surely no-one would ever do that!'. I just can't get my head round the thought process. Even if it is his opinion that you can safely drink more (although in honesty it sounds like he couldn't care less about the safety of your baby) this must be entirely your decision and his attitude seems selfish in the extreme.
Has all this started since you became pregnant? I wonder if, to give him some benefit of the doubt, he's having a hard time coming to terms with the changes in you, and your life together, and just expressing it really, really badly. I note that he's always had this issue of being rude to his parents (can't help but feel that them having taught him a little more respect in his formative years might have helped everyone enormously) but he does at least have enough self-awareness to feel guilty about it, if not the self-control to stop himself from doing it.
To be honest, it sounds to me like it will get worse once the baby arrives - obviously I hope I'm wrong and he'll come around! But he seems to be acting like a sulky child who can no longer be the centre of your attention, and that's not going to get any better once you have a baby to look after. And sorry to say this, but if drinking is what he really likes to do, what kind of dad is he going to be? Don't get me wrong, my brothers have perfected the art of nappy changing after vast quantities of red wine (possibly this improves the experience!) but none of them have the sort of sulky tempers that get worse for the booze.
As others have said, I think you need to tackle him about this if you can find a way. Next time he feels guilty about his attitude to his parents, perhaps? And certainly don't take any crap about not being tidy. You've got enough on your plate just now.
Also I'd say don't cut yourself off from your friends. They're not just there for the good times, after all, and it sounds like you could use some real life support as well as Mumsnet just now.
Best of luck to you.
