I'm definitely aware of my shortcomings and have detailed them to her. Not communicating on the bigger issues, not speaking her love language, needing to let the small things go. The usual stuff most people are guilty of in a relationship. I'll be picking up a copy of DR.
The problem is that you arent going to repair anything through your words. Now is your time for actions. What will you do in yourself to make consistent change? Telling her youre 'going to change' is not really useful. Im sure youve done that many times before. But changing for her is not lasting. Plus, it will be seen as 'too little, too late'. So, now is a time to make improvements to yourself. How will you improve your listening skills? How about your ability to validate? Patience? Communication? etc
Instead of focusing on her and the D...focus on this stuff in your life.
