Dropping by to let you know I've sent up some prayers for your wife and hope all turns out to be okay with her health. I can only imagine the weight of that worry on top of the already stressful situation for you and your loved ones right now.
I am not surprised she asked for a delay in divorce proceedings. My advice is to take things day by day for as long as that works for you. Only you will know when the right time is to move forward, one way or another.
