You can miss someone deeply and still know distance is the right decision.

Missing someone is not evidence that the relationship was good for you. Affection and harm coexist easily, and the absence of a person you loved will hurt regardless of whether being with them was sustainable. Confusing the ache for proof of a mistake is how people return to situations they carefully left. The grief is real and it is not a verdict.

When the missing gets loud, write down clearly why you made the decision, at a moment when you can remember it. Read it when you need to. You can grieve someone fully and still be right about the distance.
