Does a divorce occur if it crosses one's mind upon saying, "A woman endures what comes her way," especially with prior intrusive thoughts of divorce, and saying, "It's no longer useful; I'm tired of seeking your رضاك (satisfaction/pleasure)," without the intention of divorce?

Divorce requires intention and pronouncement. Intention is the act of uttering the words of divorce with the aim of dissolving the marital bond. Pronouncement can be explicit or implicit (kinayah). Implicit pronouncement (kinayah) only constitutes divorce if there is an intention to effect it. What you pronounced contained neither the intention nor the explicit words of divorce. Therefore, your wife remains under your marital bond. Do not pay attention to whispers [of doubt] and seek refuge in Allah from Satan.
