FYI, my father is not involved in my life. FI and I are paying for the majority of the wedding, but both families offered to help. The ceremony site is an old building that was a Catholic church, but is now a recording studio/concert hall. The officiant is a family friend, so I didn't think "request the honor of your presence" was appropriate. I also don't know if any of the above should be capitalized. Feedback is appreciated.
