Is the husband’s statement: “Good, I’m relieved of it” – meaning his wife’s adornment and makeup – considered a conditional divorce if he did not intend divorce by it? And is the wife divorced if she adorns herself for him?

Divorce does not take effect except through its explicit pronouncements, or through allusive words coupled with intention. What the questioner mentioned is far from the pronouncements of divorce. The cure for obsessive whispers (waswasah) is to turn away from them and seek refuge in Allah from Satan.
