First off, your W doesn't respect you because if she really dissatisfied with her life as you claim (personally I think you've overinflated this), then she's looking for a strong male figure to support her emotionally and financially.
You are currently unemployed and went into a drinking binge. Which pretty much destroyed the two things she needed the most. I suspect it's the trigger that stopped the sex.
She's looking for someone else for validation of her own character. She's looking for a MAN. What have you done on a positive note to show this?
How hard have you been looking for a job? The OM built up her self-esteem. What have you done to do the same?
From what you describe, she's not just unsatisfied with her life, she's unsatisfied with your lives together.
M-43 W-40 2D - 9 and 5
Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
