Particularly this part; "In our case it came back because I made the decision, independent of her, to be the best husband and father I could be regardless of her choice; and I refused to quit on the marriage, but I accepted that she could choose to quit."
I guess that is the balancing act of which I'm speaking. How to engage while disengaging. Love the sinner, hate the sin type thing. To radically accept and unconditionally love while being hurt because there might not be anything in return. Doing this by faith, as a sacrifice unto God, trusting that He will honor it and I'll reap the rewards.
Make any sense at all?
Physically, I could talk myself right out of any attraction, mentally and emotionally as well. Love her as the mother of my children, absolutely. As my lover? With a little work, that can be gone due to her actions and words.
So I choose to love her while not needing or wanting her.
