Ongoing issue; this is the latest of several similar examples.
ex-P and I split a couple of years ago and have 50/50 custody of our 9-year-old DD. The agreement was that we'd both buy clothes and shoes as necessary and these would, on the whole, travel with DD. Fine. But ex-P has form for letting me buy DD clothes, then suddenly deciding she will buy replacements/alternatives, and creating a situation where what I buy is wasted. This is especially annoying when it's an item DD specifically said she wanted, or when it's relatively expensive, such as shoes or a coat. I am conflicted about this, as I am pretty sure some of the pressure not to wear these items comes from ex-P, so I worry about saying too much.
I have tried communicating clearly with ex-P, for example, saying 'DD needs new school shoes; I'm planning to buy some, does that sound ok?' or 'I've bought DD new trainers, I'll send them in the box and if she and you are still ok with them on Monday, she can wear them to school'. This doesn't seem to make a blind bit of difference.
Latest example is this. I bought DD new trainers - decent ones, about £50, properly fitted, which matters because DD has narrow feet and finds her ankles get hurt easily if her shoes don't give enough support. I checked beforehand that she'd definitely grown out of her old ones and definitely didn't have any others. Lo and behold, she turned up at mine with a cheap pair of (different) trainers that didn't fit. This week she's due to go off on holiday with ex-P and I reminded her to pack her trainers I'd bought. The next day I took her out for lunch as ex-P had to work, and she was wearing a second, different pair of trainers, which didn't fit. She complained they were rubbing on her feet, which indeed they were.
I got back to ex-P's and said, these trainers don't fit and they're rubbing on her feet. 'Oh, it's ok, they're all secondhand' ex-P said proudly. I said, ok, but DD, you've packed the new ones I bought, right? Because I think she needs properly fitting trainers so as not to hurt her feet'. DD said yes, she'd got them. I've got home and ... they're sitting in their bag at mine.
I know DD is only 9 and I could have checked she'd taken them, but clearly, she feels she shouldn't/doesn't want to. My hunch is that ex-P is just playing games here. The backstory is that she likes to make out she is terribly hard-done-by financially; she grew up pretty poor, and there is an awful lot of performative 'oh I can't afford this' sadfacing. It makes no sense here, because for the price of two cheap pairs of trainers she could have bought one decent, properly fitted pair ... and I'd already bought a bloody pair.
What the heck do I do?
