On some level scouser, I think it's a kind of jealousy thing.
DS 1st birthday was down to him (we were in his godforsaken country) We marked the occasion with a cake. Nothing more. I wanted to take DS out, on a pony trap along the corniche. I'd spoken about it for ages. He just didn't bother.
When I next came back to the UK, I bought presents, my parents gave me presents, I bought hats and fun things so that we could have a mini-party - even if we still weren't allowed to actually go out and do something.
DH sat in the kitchen, refusing to have anything to do with any of it. The look on his face was one I'm not likely to forget. I ignored him and carried on with our little party. I eventually told him not to sit out there in the kitchen but to join in.
It turned out that in his country, they don't celebrate birthdays. Add to this the man in his land never does a single thing for himself, is waited on hand and foot and gets what he wants when he wants.. (Not with me though...)
So I think it's that they begrudge the attention being spent elsewhere.... the fuss being directed at their DC.
Not saying it's right, It's not, not at all, but I find it helpful to work out why they behave as they do. Not making excuses for him, I hate this pathetic behaviour in him, but at least I know what reaction I'll get.
DH is averse to all joy in life, why the hell would I want to go on holiday with him?
So plan your holiday, book it and go!!! Enjoy it all, cos you will, you can't fail to enjoy it with old sourpuss out of the way.
FWIW, I don't think it will give him the 'kick up the arse he needs' It very likely may entrench him further... but we all know who is right and who is wrong in this, and why should everyone suffer in the meantime, because he is hellbent on doing so?
I too once thought that DH is depressed, but you know what? It is possible to be a miserable bugger without being depressed or having a label he can lean on for sympathy.
I got from my stepdad when he was told about me going to wales without DH. To him it was unthinkable. I told him that I didn't want him to go, that he would moan and we'd do nothing. I also told him that he'd lose his weeks wages, cos he doesn't get holiday pay, so it'd be a miserable week, and on top would cost him hundreds of pounds and I'd never hear the last of it... especially if the weather pisses down all week.....
Sod what other people think scouser! Are they going to make your DD's memories?? NO! When your DDs look back, they can say how much they loved their girl time away with their mum, rock pools, playing on the beach, etc etc... not oh Aunty Jane said we would have a better holiday at home with dad refusing to go anywhere....
Sooo, where are you thinking of going????
