WIBTAH for being uncomfortable with my spouse going on a multi-day festival trip when one person in the group has had a well-known crush on them — and I can't go?

Hypothetical but want honest opinions. Scenario: Your spouse wants to go on a multi-day trip to a major city for a high-energy music festival. The group is a married couple (close mutual friends) plus one other person — a long-term friend of your spouse who has had a well-documented crush on them (at least was well known for it in the past). You fully trust your spouse not to cheat — but the dynamic feels disrespectful to your partnership.
