Is present perfect possible in "ever since [present perfect]"? I guess my question wasn't clear.
It's been a long time since I've read an interesting book.
Isn't this usually
It's been a long time since I read an interesting book.
Although this one doesn't use "ever since," I think it means something similar:
Upon close inspection [I think this phrase could mean something like "ever since"], I found that it was wrong. I have made changes so please update it accordingly.
I'm kind of confused because I thought you were supposed to use past tense with ever since and present perfect in the clause that follows it:
"I always thought it was wrong, but ever since I read it, I've been more confused."
But then, can you use past tense with past tense?
Ever since I did that, it stopped bothering me.
