Attend second lame wedding?

I have a dear friend, who attended my wedding and has always been a light in my life. She is the kind of person who cooks you a birthday dinner when an injury in your family causes your birthday to fall by the wayside. She writes cards, gives gifts, and is generally wonderful.


However, she also makes hasty decisions sometimes and recently moved to another state to be with her online boyfriend. One minute she lived in my town, the next she was taking a U-Haul to Colorado. Because of her faith, she wasted no time on the wedding (belief that marriage opens the door to kissing, sex, etc.). My head was still spinning with her move, and yet 3 months later, I was in Colorado helping to host her wedding.
We are both evangelical Christians. I share some of her beliefs, but hers have a fundamentalist flavor. There is a sense that maybe she believes my religion is incomplete because I lack some of her more stringent beliefs.
So my conundrum here is that I’m being asked to a second wedding. The first wedding in Colorado involved a lot of work from the bridesmaids to the point that it was inappropriate. I stayed in a beautiful B&B with my husband and barely got to enjoy it.
The wedding was fun in a lot of ways, but it was sparse. It was held in an undecorated church with hastily put together dresses and suits. There was this sense that I should always be working on programs or centerpieces or something. Many of the girls stayed together in an apartment, and I almost felt like I got shade for staying elsewhere and not getting sucked into the wedding prep void.
Food was potluck, there was no dancing, no alcohol.
As we were packing up all the vases and ribbons, I heard someone say, “see you at the Texas reception.” I laughed and thought, well, we’ll see if that actually happens.
Well it is. I love this girl and like the guy pretty well too. But I 👏🏻 have 👏🏻 no 👏🏻 desire 👏🏻 to 👏🏻 do 👏🏻 this 👏🏻 again.
We are literally thinking of doing a sports tournament instead. Would that be callous? How do I explain it when I RSVP no?
