Your wife is spiraling out of control. It's not your fault, but she will blame the world for everything including the sky being blue. Don't listen to her!
Please take care of yourself. Continue doing what you've been doing. Come here whenever you can.
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.
