Would you tolerate DP spending £7k on World Cup trip?

Based on your updates no you shouldn't tolerate it. However, the holiday isn't the problem. It's your DP's appalling priorities. Football is more important than your family and you building a nice home together. He'd rather go into debt which will ultimately leave you to shoulder more, rather than continue to save towards previously agreed goals or be around for his kid's birthday. The fact he has suggested this would give me the ick.

No. I would not be ok with this. And DH and I regularly do separate holidays (necessity with a disabled child) so I get needing the break and supporting one another to take breaks, but £7k on one trip for one person
is insane. We’ve never spent that for the 5 of us! If you earned double what you both do that would still be quite a consideration. But you don’t, and that’s a huge impact on the annual family finances. I actually don’t think missing a 2 years old’s birthday is too awful - they don’t care, but absolutely no
way to £7k (and let’s face it and I’m sorry but as a fellow Scot in that group it’s unlikely to end well)

Absolutely not if he has to use a credit card to pay for it and then be in debt! Some people are ridiculous. I could pay for a 7k solo holiday with my savings, but I still would not do it! As it is just too much to justify. Obviously, if you have millions in savings that is another story, but if not enough to cover, totally irresponsible, esp w a young child.

Now you've given more info YANBU.

If he has the money and it isn't stopping a family thing (holiday, necessary home improvements etc) then I don't see the issue. And if he wouldn't mind you going away by yourself.

DH goes to a different F1 race every year, costs £3-5k but he has the money, and I get to go away with friends when I want to.

No I would not be happy for him to go into debt for this. If he cannot afford to repay I hope he isn’t expecting you to pay it off. As you say if he spends all his money on that trip and leaves nothing for a family holiday or new carpets then you all suffer. There is another World Cup in 4 years. Maybe he could save for that.

YANBU for the following reasons:

1. There was no discussion, he just decided and told you.
2. He doesn't actually have the money to pay for it.
3. He has to get into debt to go.
4. The debt and his lack of savings will set you back as a family.

His poor whimsical choices have consequences for you all as a family, and that is why he's out of order. It would be different if you were well off or had good savings, as then the only sticking point would be your child's birthday, although, as she's young enough to not remember, I'd probably be ok with it.

What's your housing situation like? Do you own or rent? Whose name is the house in? Are your financial views not aligned?

Not sure about that the club world cup that was hosted there didn't go to well.

or "that was the point where I dumped his sorry selfish arse"

Yes, the debt could take years to pay off. And what if he loses his job, a not unrealistic scenario in this gloomy period we’re in?

OP, if you’re still reading this, do not marry this jerk.

the debt he’s getting in will mean the OP will be looking back and thinking that was the point where my life got harder

Thing is, in forty years time will he regret it? Probably not. A World Cup in the States will be epic, I’m not a football fan but it will be amazing.

If he's saying he'll pay cc off in a year and if that down to the nearest pound to make it work .all it takes is something major in the house,car etc to go bang.
That plan is thrown right off course ..minimum payments beckon in debt for a while.

Finance issue aside (he clearly cannot afford it) I'd be furious if my DP unilaterally decided he was going on an expensive trip. The fact it's at the expense of home improvements and a family holiday makes it even more selfish.

The fact he hasn't sat down and discussed it with you is beyind shit.

If HE can afford it okay, if he is going off your money not okay, if he will be broke and begging off you then not okay

I retracted after seeing the update

I agree. "I am doing this on credit regardless of what you think and it will result in my putting less in the family pot" is just a selfish arse.

but its NOT his money. He will be using a credit card to cover it and putting less into the joint savings pot as a consequence.

No I'd trust my dh to manage his finances if he's that much of a disaster the OP has far bigger problems to deal with. I took a once in a lifetime trip with friends a couple of years ago. My friends dh had passed the year before and it was a trip they were meant to do together so her close friends booked to do it with her. I did not have the money and wasn't going to go my dh said go it's once in a lifetime put it on the credit card we'll figure this out. And we did, the world didn't end I paid a bit off each month and I did without things not the family. That's the kind of relationship I want to be in.

even if its all on a credit card and takes money out of the family's needs?

Ok, sorry hadn’t read your update. He can’t afford it, end of discussion.

As long as he has the money available after paying his portion of the bills, I’d say it’s fine. To go into debt for it! No.
But you need to book 10 nights away too, not necessarily all in one go, but you need your share.

But is IS a financial issue. The trip will have to go on a credit card resulting in a drop in contributions to the joint pot savings.

I gave DH my full blessing on qualification to go if he wanted to but said I would only accompany if game was in Canada - I will not spend a rusty cent or set foot in US for a long time if ever again. However, looking at the costs and time involved DH is leaning toward not going - there are likely to be fan zones in Scotland as there were during the Euros that would be good fun experience. He went to the Euros last year and will again, including WC in 4 years as its Europe based. So I think, on balance, he probably won't next year. £7K is a crazy amount of money for a solo trip.
