Just got a bit of background info -
Dd1 is now 25. I had her when I was very young. However both sets of grandparents where brilliant and I trained and worked so she wanted for nothing. Her dad was useless so she got spoiled tbh of myself and her DGP.
She’s actually very driven and likes nice things so she has always worked and moved abroad for her dream job. She lost her job due to COVID and has moved back. She’s actually lived on her own since she was 19
I also was made redundant during lockdown so we are relying on dh wage. It’s a good wage and can cover all bills and two of our dc school fees. We have savings and emergency money. We also live in a nice area.
Dd1 thinks we’re loaded because of this but in reality where not. We’re just coping untill I find work.
She’s got herself a job just to see her through whilst she looks for a position in her line of work. I’ve told her she doesn’t have to pay keep.
And here is my gripe, I don’t know if I’m being petty or not..
She is literally eating everything especially the stuff I get in for the small dc eg, she will eat a whole jar of Nutella in three days. Cakes, biscuits, packs of meat. If I cook a meat based casserole she will Have her portion then continually pick at it till there is hardly any thing left for us. She’s gotten in to the habit of eating half of something before anyone else then waiting to see if anyone else take a slice/piece and if they are too slow - working her way through that.
I’ve tried buying double. It doesn’t work.
She slim but she is at the gym every morning burning it all off.
She’s using my best products that are expensive. I’m going to need to buy more in half the time I normally would.
She said she wanted to do her driving lessons whilst back home and dh said he’d pay for them. Fuck knows what out of as I’m already budgeting for xmas. She said she would have them for her Xmas present but now.
I’ve shown dh how expensive they are and he has said he will pay for the first ten but I know for a fact come xmas she will be expecting presents too. And I will not go in to our savings for presents.
She’s working now and has no outgoings except for phone and gym membership.
I never got £250 for Xmas when I was 25. She had £400 for her birthday and tbh I’m sick of shelling that much out for a working adult.
She could tell by my face at breakfast I wasn’t best pleased about the driving lessons and told me to stop being ‘tight’, dh replied ‘we will paying paying for the dc so it’s only fair’... I wanted to say back yes but they will be 17 and not in full time employment but I kept my mouth shut.
If you got this far have a mid day 
Am I being unreasonable?
