I'm so jumbled up about my motivation in all of this.

Am I wanting to tell him about my insights because I'm ashamed of how I've behaved and want to apologise?

Yes, I can tell myself this and feel it is the truth.

Or is it still a strategy to win him back? Am I looking back to see how everything I do is perceived by him and then shifting accordingly?

Try this, try that. It worked for Crimson, so give it a shot.

If I am truly focused on making myself a better person, and if I've truly let him go, why should I worry about wanting to let H know what I've come to realise about my own inadequacies?

Dear me, and thought I was getting somewhere!
