I've heard native speakers saying things like:
I've been liking her/loving her/wanting to be with her for a long time now.
They are having a bath.
I'm wanting to go on vacation, but I don't have free time.
I've been liking these south swells lately!
I'm hoping to pass the exam next year.
Is it grammatically correct to use stative verbs in the progressive tense when talking about relatively long-lasting or enduring situations, as in the aforementioned examples?
Can we use these progressive forms in formal documents?
Can we say that it has become "correct" to use stative verbs in the progressive tense, at least colloquially?
