Are my feelings unreasonable?
I've just returned from a week's holiday with extended family, near my daughter's home. Early in the week, she hosted a gathering, and I gave her my debit card to pay for the food which I often do, very happily.
At the party, I asked her for my card back as I have gone home without it in the past. She requested it from her new partner who pulled it out of his back pocket. I must have looked surprised so she explained that he'd picked up the food to help her out and she'd had to give him him my pin code to do so. I told her that this made me feel very uncomfortable but I'd discuss after the party. She said she would not talk about it and dismissed my concern.
All week, after that, her partner glared at me when we met and was very curt. I tried to discuss the issue but he told me he was extremely offended that I thought he'd run off with my money, and he walked away from further discussion. I hadn't thought that at all; he's a successful businessman, but I'm not sure why i feel so uncomfortable about the matter. I just feel my bank details are private information.
Neither of them are talking to me now. What should I do?
