The sentence is " I was once intrigued yet confused with/by all the things that I could supposedly do with my meagre salary"
Why is using 'with' Wrong ? I thought 'with' means you are in possession with another thing. In this case, the person is with the 'things' that he could do with. He is in possession of his salary .
So I'm confused why 'with' is wrong , and 'by 'is the answer
