Input: A few months ago my wife attended a school meeting for my will be middle school daughter to go on a 8-10 day trip to Italy as apart of a school group at the cost of ~5K USD.  Cool, right...It's expensive for us but it's an experience we'd both like out daughter to have.      

Last week I started to ask about chaperones and who they would be and my wife revealed she's going to be one at the cost of an additional ~5K USD.     



So, I'm pretty upset and hurt that my wife is going to Italy without me and not tell me about it until I started asking questions she couldn't avoid without lying to me. I also need to add the financial aspect is upsetting as well.  While I live a relatively comfortable life I never have money to do expensive fun things like go to Italy which I would love to do. AITA for being extremely upset and hurt?        

Thanks for your input.
