Sorry that you find yourself on here. You won't find a better group of individuals to help you try to get your M back on track. Just have faith and patience.
"She has decided that she is in Love with a man that she claims is deeper than me emotionally and understand her better than anyone has."
Is she right? Since you've been M'd for so long, it's pretty easy to "forget" dating your spouse or seeing her as a passionate woman. Did you let that fall off?
"trying to give wifey everything she ever wanted (now she says it was me trying to control her)."
That's a bit of an over-generalization. What type of things did you get her that you say she wanted?
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.
