In the holidays I went to visit my best friend who lives abroad. At the time I booked the tickets she was single and we had a lovely girly week planned. As my ticket was so expensive, she had said she would pay for the activities while I was there (although that didn't really matter to me - I would have gone anyway). Anyway, less than a month before I flew out, she met a new boyfriend. He spent the entire week (24/7) with us, and came on all of our trips so I spent my week being the gooseberry. My week was pretty miserable after he arranged for him and her to go on 'couples dinners' with other couples he knew, with me just sat there on my own. We also went away for a couple of days - everyone else there was in couples - would have been fine if it had just been me and my friend but they sat together then entire time and I spent most of the time alone. In addition, she paid for him to get into everything leaving me to pay for myself - I was a little annoyed as after what she had said I hadn't saved as much as I would have liked and am still paying for it now. Since I returned home I have not heard a thing from her - not even a message on my facebook wall. I'm really torn over what to do over our friendship. I'm quite hurt (although if I am honest not entirely surprised) that she would treat me like that after I went to so much effort to visit. I'm so tempted at the moment to just cut all ties but not sure if it is a knee jerk reaction.
