Any advice and words of wisdom from those who have been in similar situations are greatly appreciated.
My FMIL has been battling cancer for three years. 2 months ago, her doctors put her on a trial that they were hopeful about; on Tuesday we got news that it was not at all effective. The cancer is growing aggressively, and while this is not the end of the line as far as her treatment options, it has given us a wake-up call that if she does make our May 2018 wedding, she may not be in any condition to enjoy it.
While my FH feels like he is sending a message to her that he is giving up hope by moving up the wedding, he has acknowledged that it's the right thing to do. (I don't know how to handle this either. I just keep saying we can cite other reasons for moving it up and simplifying.) We are considering a small, immediate family only backyard ceremony followed by a fancy dinner out. Possibly within the next 8 weeks.
