My friend is having her 40th birthday soon . It started as a plan to go to a gig in a reasonably close city (for an artist I don’t really like but hey it’s not my birthday). But it’s just getting bigger and bigger, she booked an air bnb for 2 nights and has started suggesting takeaways, booking a restaurant etc. She has suggested we split the cost for a mutual friend who isn’t working right now (I don’t disagree with this one but she’s told me she probably won’t be able to come due to health reasons anyway so it’s annoying to have to pay). But it’s looking like its going to cost at least £500 if I go. I can take the money out of savings for it I don’t really want to, it’s much more extravagant than anyone else’s I’ve been to. The only other person which I know likely isn’t going. I don’t want to let the birthday girl down (only 5 people invited) but I don’t think she’s considered the effects on everyone else. She does have form for this type of thing but also i’ve never directly raised my concerns before. I’m feeling stressed and resentful already. I think I need to explain it’s all too much and we need to think again but I don’t want to upset anyone. I’m also not sure if I’m just being a bit tight and I need to suck it up!
