I have just read all the posts...
Firstly, I am very sorry for your loss, with respect to the wedding, ultimately, I say make the decision a family decision. I normally wouldn't say that, but given the extreme circumstances... make it a family one.
I'd also like to say, that after reading all the posts, the ladies on this board are absolutely fantastic, loving and sympathetic. In all the day to day chaos, of work, life, and wedding planning, you have all banded together, in loving support of Indigo. I am very impressed.
Big Hugs... and warm thoughts.
