So my ex and I divorced. We've both remarried. Our daughter's big birthday is coming up. He loves designer brands (so do I but I haven't really got the money for them nowadays) and said to me that it would be lovely to buy her a designer bag to always remind her of that birthday (I do not care if you think designer bags are a waste of money or think we're awful people for buying them). I agreed and we decided we'd buy her 1 designer bag priced at around £720. We agreed that we'd split the cost equally and do some smaller presents separately. He's obviously continued to research designer bags and come across a vintage one that he really wants to get her priced at about £1300. He mentioned it to me and I agreed that it was a bag she'd really love because she's mentioned it a lot before but we'd decided on the first one because we weren't sure as to how easy it would be to get the second. Now that he's found a seller, he has asked me to pay the £300 and for him to pay the grand. He has a really high paying job and knows that I don't always have the cash atm (have been saving for her presents for this birthday so I can afford the prices he has suggested). I agreed. Earlier today, his wife messaged me saying that it was unreasonable for me to let him pay this much for DD's birthday. She said that it was unfair for me to make him pay more for her bags than me. I can see why she might think that but I didn't ask him to go looking for the second bag and I suggested not getting both and just getting the one but he didn't want to do that. I don't really know what to do. Am I being horrible to say that I don't think it's that unfair because he was the one who wanted to buy 2?
