I'm a little confused by your post, and what you chose as your Title of your thread.
What does your thread title mean?
Also, you state your wife had two physical affairs. How long ago were these? Does she know that you know? If so, what consequences, if any, were there? What boundaries, if any, did you put in place in your marriage after your wife's infidelity? I ask because usually when someone writes "I am loving my wife unconditionally," it really means "I have zero boundaries in place." That may not be true in your case, though.
Fireproof is an AWESOME movie, but it doesn't mesh very well (ok, "at all") with the wayward stage in a marriage, as it's classic "Pursuit" that MWD warns against in her books. It's more for a couple who have mutually agreed to reconcile, and are working at healing the marriage jointly.
