There should presumably be two likely outcomes to the Sotah ordeal (Bamidbar 5:1-5:31) after drinking the embittering waters: Either she is guilty and then dies, or she is innocent and lives and goes back to her husband.
What about a third possibility: She is innocent but does not want to go back to her husband. If she knows she has never committed adultery, she has just been suspected on little grounds (even circumstantial evidence) for whatever motives by her (seemingly) faithful and loving husband. He has the Kohen subject her to an ordeal of being publicly embarrassed in front of everyone (at the gate of Nikanor). He removes the clothing of her upper body and hair, he tires her by having her run around and hold the meal offering of remembrance (jealousies), and he subjects her to more humiliating rituals. Although the Torah says that she may resume relations with her husband and that they will have healthy children afterwards, do you really think that a woman whose husband just embarrassed her like this would have any respect for her husband anymore and would want to be with her husband? What is even worse, if the woman resents what her husband did and doesn't want to go back to him, she can't even give him a get. She is stuck between a rock and a hard place. She is forced to (re)love her husband who because of a baseless hunch or feeling had her go through the Sotah ordeal.
