Is a minor irrevocable divorce counted against my wife, given that I don't recall the exact wording of the divorce, and whether it was merely a thought or if I actually uttered it, and given that I had no intention of divorce, bearing in mind that I suffer from obsessive-compulsive disorder?

You were not in need of renewing the contract, because what you mentioned are whispers (waswas) that do not entail divorce, and your wife is still under your marital bond. So, turn away from these whispers and do not pay attention to them. Beware of giving in to them, as their consequences are grave. We advise you to consult the psychological counseling section.
