This is a bit like the other thread where the OP was wondering if it was reasonable for her P to book a stag do costing £1500 that they couldn't afford when she was pregnant.
Usual slew of posters going oh I can't understand these people who don't have separate interests I love my DH going away it's so relaxing.
It's a different matter to support your DH's interests when they don't directly contradict those of you and your family.
Has anyone tried going on holiday alone for three days with a 2,4 & 6 year old with an elderly mother? If not can they imagine that it would be in any way enjoyable? I'd be ok with DH not coming out for 2 days, although I wouldn't be in any way happy, but that's because we have one 7 year old and it's an entirely different matter as I know I would be able to look after him safely.
Do people actually know how package holidays work? As in the OP booked it a year ahead to get what they presumably decided upon at a reasonable price because it is half term ( oh and btw I'm not sure on what planet booking holidays on the only dates you can make due to your job could be viewed as controlling). The chances of adding an extra bed half way through are slim I would think and there would be an additional cost for the extra flight home. In any case why is the OP the one who should be investigating all this, her DH is the one with the clash, I don't see any posters at all saying that he is the one who should be sorting it out.
iiiiii - I do believe the DH is prioritising football over his family, of course he is. If they hadn't already booked the trip then I'm sure she would send him off with her blessing and her family would miss out on their trip abroad, these things happen. But its already booked. There is no parallel universe where they can go back in time and unbook it and not lose money.
The solution the OP is fair, not controlling, but fair. Her sister goes instead, if I was the OPs DH I would be delighted with that, he gets to go to the game and his wife is reasonably happy and they don't have to spend a fortune on extra flights for him oh and his children aren't put in danger by having one adult trying to look after 3 of them.
Haven't discussed this thread with DH - have a horrible feeling his views may not coincide with my own
