Been married 20 years. Been in similar situation - with table turned.
(I was thrilled when someone flirted with me).
Her Path:
- confess sin
- repent
- find an accountability partner (even women need one)
- put energy into your relationship
From your perspective:
- forgive the sin (let it be dead --- forgiveness is a decision, not a feeling)
- put energy into your relationship. I'm not talking about programs - Weekend to Remember is a framework - not a solution. I'm talking about relationship. Invest time and money into it.
Flirt with your wife --- play footsies in church ---- make eyes across the dinner table --- make out in the elevator --- read Song of Solomon together. Surprise her.
The hardest part for me was to leave my expectations at the door. I don't really expect my wife to be romantic --- I expect my Lord to be Lord and God over the situation. I turn to Him for Love, Grace, and Mercy. Lo and behold - my wife feels more free to be my lover, as well as my wife.
