About that Boyfriend!
Of course, I can not predict the success or failure of a relationship. Nor can I tell you whether you still will go on the trip together. But there is one thing that I can assure you about: forgiveness is not part of the deal.
Relationships are a mutual bond. You should always feel free to express your opinion. Just sit back, accept the fact that he might not take you on the trip and play your card as an adult whose life will go on, trip or not.
