To think my house guest is BU?

[GunpowderGelatine]

Have my mum as house guest staying for a week at the moment. But of a strained relationship - dread her visits as she doesn't contribute to food, petrol etc and will buy milk but get the £1.50 off me for it when she's here.

My brother has driven through from his home 2 hours away and I wanted to get food in for when he arrived. Went in the car to M&S food to get a few nibbly bits (this was for lunchtime, we're off out for an evening meal). DS fell asleep on the way so mum went in to get bits, it was agreed she'd go half, I said that's fine just get some pizzas, quiches etc. Said don't get sweet stuff we have loads that needs eating (cheesecake etc).

She spent £110!!!!

We had, among other things, 3 full medium sized cakes, crates of beer, bottles of Prosecco (DH And I don't drink) beef joints, mango slices and watermelon slices at £4 a pack each, a fucking roulade and ONE pizza.

Now she's asking me for £55 contribution. WIBU to tell her fuck off no. I was expecting to spend £15-£20 and would have been happy to pay for it all myself, she offered to go halves.

You don't owe your parents anything. My children won't owe me for raising them and loving them, I chose to have them.
People who say things like "but it's your mum/dad!" must have had nice, normal parents.
That said, perhaps your communication with your mum could be changed so she knows exactly what you expect of her. Next time give her £20 before you send her in.

My mum is a royal pan and I’m NC but if I did have a relationship with her and she care to stay, I would ensure I had all the things in I know she likes, incl booze. I would want to treat her and make sure she was comfortable and had everything she needed.

You don’t drink but she does and she is your guest, I really dont understand why you would have anyone to stay and not do this. You have said that it’s not because you can’t afford it, just because why should you. You ‘should’ because she is a guest in your house.

Why would you expect her to contribute to food when she comes to stay?

Our families live too far away for just an afternoon visit so they stay with us, and we stay with them. We don't expect a contribution for food and neither do they. I think it is odd to do so.
