"I have just wanted to ask a question."
I was told above sentence is not valid and natural to refer recent past and "just" cannot mean here "very recently".( Recent past usage of present perfect tense) Because "wanted to ask" denotes a state not an action therefore it doesn't mean an observable completed event where there is a start and finish.
Therefore the sentence " I have just wanted to ask a question" only means a situation where "wanted to ask" has been continuing for some time to the present and "just" means "simply" or "only".
Can you explain if this is true? Only rule with regard to stative verbs in English is they shouldn't be used with progressive tenses. I haven't come accross any information that explain my example in any English teaching material even in present perfect tense subject.
