Hi Viceidol,
Thus far we have examples of three tenses: simple present, present progressive, and present perfect progressive. As Philip says, the present progressive seems awkward with "I am wanting." I don't know if it's considered incorrect.
The other two seem fine, correct, and natural.
I want to go to Europe. (simple present)
I've been wanting to go to Europe. (present perfect progressive)
I expect I might use "I am wanting" (I'm wanting) in certain cases similar to "I'm thinking."
I'm thinking I might run out of gas. I'm thinking I shouldn't be spending so much time on my homework.
When I switch from a standard (stick) shift to an automatic transmission, I'm wanting to push in the clutch when I come to a full stop. I'm wanting to ask her for a divorce, but I keep thinking about the children. Somehow, these seem natural to me.
I am wanting has the same feel as
I keep wanting.Best wishes, - A.
Edit. Hi Yankee, I got interrupted while I was writing this, and didn't see your post.
