LSG you are right! I am awful at the "what ifs" - I'm a big planner and so I get less stressed out if I kind of go over scenarios in my head beforehand. I'm SO nervous! I guess I'm kind of nervous that his reaction won't be what I hoped it will be and it probably won't. I plan to get there before him (or try) and then he would have to choose at the ceremony whether or not to sit next to me - I obviously hope he sits next to me but will be sad if he does not.
You are right about the ring. My plan was to always wear until divorce is final. He won't say anything about them... not his kind of personality.
I am going to do my absolute best to have a BLAST at the wedding. I am going to keep concentrating on my FRIENDS and THEIR day! I am going to make myself get up there and shake it even if I don't feel like it!
