Hi IbIP - hope you are actually asleep now. (I have weird insomniac nights when I wake at 3-4am and that's it)
I guess there are two sides, you need your sleep and it's not fair that you can't go out and enjoy yourself too.
But equally I did find that it took my DH a good few months after DS was born to "get" that life had changed and he therefore had to change too.
We have much longer to get used to the idea as it's our bodies that are feeling every change through pregnancy. Men don't get that, so apart from watching us, they are that bit removed from it all. Also when the baby does appear, it can be pretty scary and a lot of men do freak out slightly and try to carry on like nothing has changed. My SIL has a 5mo DS and her DH has been on 2-3 weekends away and one week away, plus lots of nights out. I think because their DS has been quite hard work and colicky
My advice? Talk to him about how you are feeling, but equally let him go out now and when the baby first arrives. Babies are not always that interesting when vv small (at least for men/other people), if you let them (DP) get used to them slowly, you'll find they are much more engaged a few weeks/months in. And by then you'll be ready for a night off/away.
I think forcing a baby on someone (even if very much wanted) or a lifestyle change from"freedom" to staying in every Friday night can be a really tough/risky thing to do.
Sorry epic post- hope it makes some sense! And FwiW I don't really like AIBU forum
