whatatosser, feel free to rant here, yes everyone has troubles of their own but that doesn't make yours any less important. And it can really help to get stuff down in black and white.
Now, I know people in Stockholm, I can put a hit out on him if that will help?!
Sounds like you've made a lot of sacrifices for him and his career - which is fine, I'm not condemning that at all. But the reason why you don't have a group of friends where you are is because you are constantly moving around for him and dh should acknowledge that, not throw it up in your face in this way.
Ordinarily, like you I wouldn't go out with a male friend on my own for dinner or a movie, although I have suggested it as a possibility to my dh but that's because he is too ill to do any socialising so that's difficult for me. But I would always be very up-front about it, it would be a once-in-a-while deal and nothing like what your dh seems to regard as normal.
He does seem to have a bad case of NFA and has decided to carry on his life as if he were still in the pre-child days. Since you can't share in that, he'll just go out with people who can.
He has a very stressful job - you are doing an INCREDIBLY stressful job. He has to work late - you have to work 24 hours a day.
Having said all that, I wouldn't make any sudden moves at this stage. These are early days for you all and there is stress all around. Just adapting to the reality of being a parent is incredibly difficult and impossible to explain to anyone else. For blokes, for whom life can often go on more like before (although he's taking the piss in this regard!) I think it can take longer for the reality to sink in.
Equally, you can't go on as you are. I'd be tempetd to force the issue if I were you by emptying the current account so that he can't withdraw any dosh on his next night out (report his cards stolen as well, ha ha). Obviously I don't mean go and spend it all, but move it to a savings account. If he won't deal with things when you try and discuss them with him properly, maybe he will when he is embarrassed in front of his mates? I don't think it's a win-win strategy but he sounds like he needs a short, sharp shock and short of you moving out, I don't know what that's going to be.
