While I agree that we need to be patient, the word “confidence “ isn’t absolute it’s a fluid term that can solidify or break with actions.
So nothing wrong when your confidence changes as things happen!
It’s like you have confidence in your partner and they break all their marriage vows and you intend to divorce and someone questions why you married someone you had no confidence in?
For me, I can afford to wait as long but some can’t and they have every right to vent, it’s their money! Not mine.
