Apologies if this is posted elsewhere- have just joined and thought I'd posted, but can't find it now. A friend I have known online for a couple of years, but never met, messaged me 2 weeks ago as she was going away this weekend with her bf and 2 other friends, but had now split with her bf and asked if I would like to go instead. The weekend had been booked and paid for months ago on her credit card. It was an event I would have liked to attend so I agreed and foolishly as it turns out forwarded her £150 immediately rather than pay on the weekend. Over the following 5 days I became unwell, resulting in referral to hospital and being signed off work sick. This is highly unusual for me - haven't been sick in years but I am really unwell. On telling my friend she initially said she would have to reimburse me, but this soon changed to her saying she couldn't re-sell the ticket and has used my money to pay off her credit card. I suggested the 3 still going could contribute an extra £50 each, as would have been the case had I not already given her my £150 in good faith, but her stance is 'tough - you changed your mind' and ended in her sending a 2 minute voicemail rant saying she has done nothing morally wrong. If I had simply changed my mind I would feel different but as I am genuinely really unwell AIBU in feeling I have been taken advantage of? If the situation was reversed I know I would feel compelled to reimburse her. I know legally I don't have a case but morally? Really? I would appreciate your thoughts.
