I'm sorry about your MIL. Sounds like she's in a great deal of pain. She's put a huge burden on your h by discussing the option of suicide. Has he talked about how he feels about this? Are they expecting him to help w/this suicide pact?

I do hope that they will consider something else and not take their own lives as this would leave a terrible burden behind for those who knew what they did. I will keep them in my thoughts and prayers. The situation sounds like it is getting very serious for her to discuss it w/her son. I pray that they find another solution and can enjoy what little time they have left on this earth and allow God to determine when they shall cross over.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
