I've arranged a weekend away with friends. I paid from my own account £600 for the accomodation and £80 for my own train (week end away is nearer for her) I have also done a Sainsburys order with my own money for wine/breakfast when we arrive. Out of the 6 of us im the only one who has 2 kids and works part time. Everyone threw in nominal shared amount. Then I had msg to request £3.50 refund as she had worked it out and was pissed off at being overcharged. Almost demanded it instantly by PayPal. Later that day she was bosting about buying Sophia Webster shoes. I was actually out of pocket by £35. But just gave the 'rounded up figure for ease'. She msgs on a group chat and non of the others told her to pipe down. I don't even want to go now. I'm so fucking furious.
