I have question regarding how to use "wish" in its past tense.
I know you use "wish" to say that you want things to be different from what they are.
For example, if you are poor, and if you don't want to be poor, you might say
"I wish I were rich. "
If you said something stupid and you regret it now, you can say
"I wish I hadn't said that."
How about if you were poor in the past and you didn't like to be poor back then but you don't mind being poor now. Can you say
"I wished I had been rich"
"I wished I was rich"
"I used to wish I was/had been rich"?
Similarly, if you had said something stupid long time ago and you used to regret it, but now you don't. Can you say
"I wished I hadn't said that"
"I used to wish I hadn't said that"?
Thank you for your help
