Thank you all again for your very helpful comments. I come back to par 1864 of the Catechism. It works if you consider “forgiveness” and “mercy” to be equivalent. I have not seen, in the comments here, a better Scriptural or Magisterial reference than this:
“There are no limits to the mercy * of God, but anyone who deliberately refuses to accept his mercy * by repenting, rejects the forgiveness of his sins and the salvation offered by the Holy Spirit.” [Cf. John Paul II, DeV 46]
So here is where I think I have come out:
God offers forgiveness to everyone. The offer must, however, be “accepted” for the forgiveness to take effect. No one actually enters a state of “forgiven-ness” until he accepts God’s offer of forgiveness by repenting.
Therefore, we likewise we must offer forgiveness to everyone. I can, therefore, say to someone who has gravely injured me, “I offer you my forgiveness; I pray that you will accept my offer by repenting of what you did to me and thereby actually be forgiven.” Although I have offered them my forgiveness, they are not actually forgiven unless they accept it. And the only way to accept it is to repent.
It gets a bit confusing to me because the offer of forgiveness is “unconditional” in the sense that the offender does nothing to merit or deserve it and God will never withdraw or revoke it up until the moment of death. Yet, the offer is “conditional” in the sense that repentance is the “price” of acceptance of the offer.
Perhaps the language gets sloppy. I have often heard it said that “God forgives everyone.” Or that “We must forgive everyone.” Perhaps a better way to say it would be “God offers forgiveness to everyone.” Or that “We must offer forgiveness to everyone.”
Thoughts?**
Yes the problem is the language does get sloppy.
It’s a fine point but an important one.
Forgiveness is an initiative on the part of the one offended. Response is required for the other party to experience the grace offered. But forgiveness is a powerful reality independent of the response.
*Forgiveness is an objective reality independent of the response of the offender.

The cross is durable proof of that. Christ offered us reconciliation with God, and we responded “non-serviam”. And still, he paid our debt in the midst of our refusal. His action, and his offer, is real and enduring despite our response.
That is really, really, important to keep in mind.
Habitual sin can cause us to despair of God’s forgiveness.
Habitual sin on the part of others can cause us to fatigue of forgiving others.
If we are going to be forgiving as our heavenly Father forgives us, we have to let go of the demand for a just response on the part of the offender.
We can encourage a response, but we can’t enforce conditions on forgiveness.
