“Forgiveness is preceded by repentance. “

If she entrusted herself to Christ for salvation, yes, that implies a change of heart. That said, at that moment, all her sins, past, present and future have been dealt with judicially and paid for with the blood and death of Christ.

I believe we must, by self examination, look inward on a regular basis to see that we are living a Christian life. How could future sins ever be forgiven if they are never addressed?

Character flaws are specific - it's required that they be addressed individually if they are to be set aside and forgiven.
