Ok - so DD's school is one of those ones that 'offers' a really expensive trip abroad to NY - basically costing an arm and a leg. DH and I said that we can only do for one what we can do for the other children, of which we have 4, so forking out for what would eventually come to £8000 is not doable (the trip would be £2000 with equipment, so that times 4...). DD and DS1 are from my previous relationship, DS 2 and 3 I had with DH. We also said the money would be far better spent on learning to drive. The 'aim' of this trip is to go to Broadway, go to an art gallery and go shopping. All of which could be done in London for £100 + spending money. Instead, this trip is £1000 + spending money for the week, food etc.
We said for her not to apply, as we wouldn't be able to let her go if she got in.
DH has just found out that she's applied, got in, and her dad is paying for her to go. Bearing in mind that XP doesn't pay his full maintenance proportion as apparently he can't afford it, we're furious that a) she's gone behind our back, applied and lied about it b) he's using the trip as a popularity contest.
There is nothing advantageous about going on this trip other than the kudos of going, and we just think it doesn't teach DD about working for things she wants - it just teaches her to run to her Dad when she disagrees with our decision.
Legally, it's also tricky as he doesn't have LPR, so if he's signed a form to give her permission to go, it's illegal. But WTF do we do now? If I stick to my guns, I'm the bad guy again, saying no, but if I back down and let her go, she's getting her own way after being sneaky about it!?
