Counting instances of "i"

Hi All,

I'd like to count instances of the first person, lower case "i" when used incorrectly in a sentence. For example, in the following sentence:

"i don't like when i have to drive home in the dark."

...would return "2" because the first person i was used twice. I've tried to use Regex for this, but it ends up returning "5" as it's counting all of the i's in the sentence.

I've tried:
\s+i\s and
\bi[ ]

Any help is appreciated!

Try: \bi\b

You're looking for i as a word, after all.
