I am slightly outside of the rules of this sub so I apologize in advance. I haven't had the argument yet, I more just want a little guidance....

My friends and I are late 20's unmarried guys. We did a guys trip a couple years ago to Europe and it was great. Planned it on a budget, stayed in hostels, drank too much, but had a great time. I found out today the same group minus me is heading to Switzerland for 10 days in May. I have been friends with these guys for over 20-years. Am I the asshole for feeling left out? What is the best way to open the conversation to say I was sad to hear I wasn't included?
