Yes and Yes
That one(1) time I was young, dumb and full of ... stupid
Then suddenly after 2 1/2yrs, I was no longer her boyfriend
AND, her best friend was no longer her best friend ... nor my new girlfriend

I thought I could change her and furthermore painfully learned you can't change anyone that doesn't want to change
