Example:
"I don't understand why she likes him or when she started liking him."
or should it be
"I don't understand why does she like him or when did she start liking him."
?
Should I used the question form for the second sentence? I want to know if you need to use the question form if you are asking a question in a much larger sentence that is not a question itself.
I want to know if I can ask "I don't understand Why he/she did/wanted something" without question form.
"Why you did this" vs "Why did you do this"?
