Input: Just some backstory here. I am currently living at my girlfriend's mum's house as a temporary arrangement due to undergoing spinal surgery in November 2018, as the shower and other facilities are easier for me to use due to my immobility. 

I purchased a pack of rather expensive Tesco's Finest Ham Off the Bone yesterday, in which you get four slices per pack. These are for my dinner to take to work as I work shifts.

Today, I was sat in the living room watching the football, when my girlfriend's Auntie walked in the house to take herself and her Mum out for clothes shopping. This was around 3:15pm in the afternoon. As her Auntie walked into the kitchen, she said she was hungry and hadn't had anything to eat. My girlfriend's Mum then offered her some snacks, or to make a sandwich for her. My girlfriend's Mum then opened the fridge, looked inside for sandwich filler and informed the Auntie that there was some ham. As it happened, there were two packs of ham. One had around 12 slices in, was a bit thinner than the ham I purchased but was by no means cheap and nasty. 

Now, when the Auntie looked at both packs of ham, she decided that she wanted the pack which I had bought, which contained only four slices, was expensive (£4.00) and was for work. The Mum then explained that the ham belonged to me, but that she's sure I wouldn't mind if she ate it. At this point, I explained that the ham was actually for my dinner at work and only has four slices in, which in fact aren't even large slices. They would be sufficient for one sandwich, as they are like bacon medallions but smaller. 

I said it was quite expensive as ham goes, and that I bought them for work. I then said what is wrong with the other ham? The silence was deafening. I went to sit back down in the living room, and my girlfriend came in to state how "rude, selfish and ungrateful" I am. I was incredibly surprised by this as my girlfriend in the past has actually made comment on how ill mannered and cheeky her Auntie can be when in someone else's house as a guest. 

This has now caused a rift, and I am now feeling ostracised and out of place, and to make matters worse, my girlfriend was supposed to be taking me out for a birthday meal tonight. But that has been cancelled, on her part. I'm in genuine shock.
