Two things to clarify,
1. There was never anything sexual about my thoughts of contacting her.
2. Contacting her was purely about reconciliation.
I wont bore you with details, but making amends for past mistakes is an honorable trait. Two books which speak to it are the Bible and The Big Book, granted both are foundationaly spiritual, but sage advice nonetheless.
The fact that she is a she, and me a he in a committed relationship only comlicates details to a point in fact of telling another person, "I'm sorry" and that is all.
Its amazing that we as people can't take something for what it is - that being an honest admission by one person of being an ass to another - and see it as being intrinsicly beneficial.
I once heard that forgiveness isn't about forgetting (the notion that someone *forgets* another is ridiculous and false on its face, no matter how psychologically buried it may be), but forgivenesss is about freedom. I feel in some ways, making amends is about releasing someone else.
But, all that being said, its an old girl friend. I'm in a committed relationship with my wife, its messy on many fronts. What I will say is the reverse has happened. My wife did have contact with an old boyfried, and they did talk for a while and figure out what happened. I never once felt threatened by it.
I think the advice that it would be out of left field FOR HER is spot on, as I said earlier, and I respect that.
