Celeb, I'm another one who hopes your operation will cure your pain.
Eglantine, how wonderful that you were invited to help with the wedding preps. As long as you remember that, even if you have a suggestion or two, all final decisions are up to the bride and groom. It will be nice if they ask your opinion on a few things, but please be prepared to accept it gracefully if they don't follow it. In fact, hopefully, you're ready to accept it if they don't seek your opinion at all. They may already know exactly how they want things. Just enjoy!
Ladies, it's not so strange, imo, that some of you haven't experienced much anger. Idk, but Iv read that not everyone goes thru all the stages of grief. Luckylegs, in your case, I think it might be partly because you know you're the one who co the relationship. But you still could be mad at ed for pushing you to that point, and yet you're not, so that might not be it. I just hope all of you are able to move on eventually.
