Wow, "backsliding" is a wonderful word to use to explain what has been happening to me. I was confident for short periods of time, and then I would slip.
We had a wonderful date last night. I was able to remain confident throughout. I even phrased things the way a confident person would do so. I remained balanced.
Also, I feel reassured that our relationship has not been crippled due to my recent bouts of insecurity. She asked me questions about my past. That made me feel as though she understood me, and that she cares.
