So this week Sat - Thurs I have been staying with and looking after my 2 nephews 4 and 6, my brother and SIL asked if i could travel to see them as its half term and they need help with childcare.
We have done a few fun activities together and I have really enjoyed looking after them. Yesterday my SIL spoke quite rudely to me about something basically treating me like I'm one of her staff. I didn't confront her about it as I didn't want to argue in front of the boys. Later that night my brother made a comment and I told him I didn't like the way SIL spoke to me. He said he doesn't blame her as I have just had a free holiday and had all my meals cooked for me. I said that I have looked after the boys for them so its hardly a free holiday to which he replied so you should you are their aunt.
I feel really hurt I enjoyed spending time with my nephews but now feel like I they didn't want me there to spend quality time with them just to use me.
AIBU to feel so upset about this?
