Is the statement: "If you don't want to, the door will fit a camel" considered a divorce, and if it is one of the allusions to divorce, is it a suspended allusion that requires the existence of the condition for its realization, and is the suspension nullified, and the لفظ (utterance) remains an unsuspended allusion to divorce if the condition is undefined or the wife was not present when it was uttered?

It appears you are suffering from waswas (obsessive whispering/thoughts). If this is the case, then know that waswas is a serious illness. Therefore, you must turn away from it and pay no attention to it. You should busy yourself with dhikr (remembrance of Allah), reciting the Quran, sitting with righteous people, and seeking a way to cure this. Since you have presented this matter to many muftis (jurists who issue fatwas) and they have all given you a fatwa (definition) that this is a case of waswas, you must accept their fatwa and stop moving between muftis. Live with your wife as if nothing has happened.
