It is good to hand him over to Heaven. Looking back on my life and my breakups, I’d say the best thing is to either look straight at what just happened, drawing lessons from it, or otherwise to turn your mind to other things. The sooner you can discard the sidelong glances that are neither profitable thinking about him nor forgetting the whole thing, the better.
Pray that he lives long enough to repent and accept his deliverance. Resolve that you will never ever put him in a position of trust again. Look at the path you just took, and ask where the signposts were that you missed this time, but should be on the lookout for next time, so that you ever again find yourself on the wrong freeway you will not miss the closest off ramp. Besides that, move on. Find a thought to think on when he comes to your mind, and gradually replace his place in your head with those things better suited to your current life.
Do take the time and find the right counsellor to go through the debriefing with you, though. You’ll be glad you did.
Mazel tov, BTW! It may be hard to see when the salty water of the Red Sea is still clinging to your feet, but you have been given a deliverance. Praise the Lord for it!!
