We have my DSD (10), my DD (8) and a 6 and a 2 year old together and I'm pregnant too. It's DSDs birthday next week but she'll be with her mum so we're celebrating this weekend. I've arranged to collect three of her friends in the morning and I'm taking them to a theme park for the day. I've booked a restaurant for dinner on the way home and arranged for her friends to sleepover afterwards. I've researched, ordered, shopped and paid for and wrapped her presents. I've arranged for a family dinner to celebrate on Sunday, then on Monday for a surprise we're going to collect the pet rats she has wanted forever.
Tonight DSD asked her dad what he'd got her for her birthday and whether she could have one present tonight. He laughed and said to ask me what she's getting. She then asked if he'd actually done anything for her birthday or left it all to me. He said that whatever I organise or buy is from him, too. She looked unimpressed with that response and I was too. I have spent hours organising her birthday and presents. We don't share finances and I've paid for everything, the same as I do with all the DCs birthdays.
I realised it annoys me that he takes the credit and likes being there for the photos and thanks but doesn't actually do anything. When I told him this tonight he said he'll be sure to point out to the DC that next time they're warm from the heating it's thanks to him paying the gas bill and nothing to do with me 
AIBU to be pissed off with his lack of interest but claiming of credit? It's the same at Christmas, he's as surprised as the DC when they open their presents and doesn't pay for any.
