Lan, I hope you find your balance (game plan). It's tough living with an unhappy W. I titled my thread "Turbulence and Connection" during this stormy phase.
All one can do is keep investing in self-care activities and interests, connect with your W when she wants connection, give her the space to work-out her issues, keep being kind to her, but hold your ground when she demands what you consider unfair.
I hope that your W gets weary of being unhappy most of the time, and begins to make some effort at happiness. This is what happened in my situation. Scaling back her work hours to part-time was also the catalyst that moved my W and us into the next phase.
Does your W need to make more of an effort at being happy (less focus on negatives, less rumination, acceptance ot things beyond her influence, self-expression), or is there a lifestyle change that needs to occur (more fun, less responsibility, more balance)?
