Not a covenant keeper by any means but I have read a lot and thought a lot about this stuff. I love your spunk, but I think if you want to have a future with him you have to learn to curb your anger and avoid the cheap shot even when he has paved the road for you. Acorn says on her thread over and over again about zipping her lip. This seems very hard for you, as your parting shot shows. If he does try to return, he will likely be a scared kitten and will have a lot of fear and worry about your reactions and your ability to forgive. I think you have to decide: do you want to be right (or say your piece--fill in the appropriate blank) or do you want a chance for a future relationship with him?
I know Goner takes a lot of heat for her directness (and of course she is not alone) but refraining from name-calling of the OW and not giving him unkind names (our subconscious and brain patterning really are affected by this stuff), being kind and compassionate without allowing cake-eating, and being the woman only a fool would leave are really your best shot here. He has to see something that is desirable to him (you have to be the better option) and he has to see the opportunity to approach you before he will.
Have you ever read Happy_Again's posts on the DB board? Most are purged, but there are bits and pieces posted here and there. I have not read any account of a returned MLCer that seems more raw, real-time, and instructive. I heard the exact words out of my H's mouth that he spewed against his poor wife. I imagine everyone here did too. Like Stayed's husband, he recounted what made him want to come back, the doubt he had that they could correct the problems, and the anger he felt at his wife. Very raw stuff.
Mine is a slightly different flavor than a lot here. He is a vanishing clinger (but we do have a geographical distance that could account). He has come back and tried to come back several times. I can now see the approach a mile away. I think if you settle in to yourself, your life, your happiness, out of the corner of your eye, every now and again, you may get a sight of him leaving coffee on your porch.
When and if that happens, keep your eyes on you, your expectations low, and your heart open.
