It sounds like a wonderful opportunity, especially if you can fully face each other!
Perhaps one challenge is to not allow anyone else to get in the way, including the image of someone else. Similarly, perhaps you must deal with aspects of yourself that are peering back to what was, should or could have been with your former partner, or which are in other ways peering a different direction.
I do not, of course, know your personal history -- but grief can be a wonderful blessing, allowing you to cut to the core of your being, to be naked before God, wounds and all. And thus heal in the Holy Spirit, letting to let go of that which you no longer need to carry.
It sounds like you�ve already moved far along that path.
Blessings and best of luck, Brother Jaan!
