Two wedding on the same day; in one, but really want to go to the other
I am in a wedding in four weeks and the bride has called it off once, but it is back on again. I do not support the wedding and think the marriage is doomed, but wanted to be there for my friend and agreed to be in the wedding party many months ago. What makes it worse is that there is another wedding the same night which would mean a lot to me to attend. This particular couple is very close to me and I feel horrible missing it. How do I excuse myself from the first wedding, which I am in, to spent a little time at the 2nd wedding?
