An old school friend is getting married and when she first asked about her hen weekend I agreed to go, paid £50 deposit. Since then I have had a baby and my OH has lost his job. This week I had an email about the hmmm weekend saying it would cost another £300 which I simply cannot afford, paying our bills has to come first. So I have had to say I cannot go. I did this the same day as the email arrived saying the cost of the weekend. The bride-to-be has sent a very snotty email saying that I should have said sooner as everyone else now has to cover the cost of my place on the weekend. But I only dropped out because it is so much more than I had anticipated and the full cost was only mentioned now, previously there had only been talk about "keeping costs down" and I'd expected half what it's costing. Am I being unreasonable considering the total cost has only just been revealed?
