I wouldn’t make a big deal out of it. Sometimes people get burned in their dealings in life. The Chosson and Kallah should have included you in their life, especially since you were such a big part of it. However, if they didn’t want to include you (as seems the case) then my advice is not to bring up the matter again. You have not lost anything monetarily, only time and effort. All I can say is learn whatever you want from this experience and move on.
