As for gifts of the relationship I learned my self worth. From that I have been able to do some great things with myself. I don't feel it is fair that she gets to take credit for that though. Am I wrong? I mean she put me through the ringer badly. Not quite sure why she should get to take any credit for my outcome in life post the relationship. Am I not understanding your statement correctly?
I understand JSF, my ex took credit for everything good in the relationship and blamed me for everything bad; it had to be that way for her because she thought so poorly of herself, and taking responsibility for any shortcomings would have resulted in debilitating shame. But that's her.
I'm not completely up to speed on your situation, but if the relationship is over and it's been a year, she can do whatever she does and it need not matter in your life, unless you make it matter yes? And your accomplishments are your accomplishments, being proud of how far you've come is completely legitimate, and if you credit the experience with her as partly what motivated you to achieve what you have, then that is a gift of the relationship, if you say so, something to take out of it that was positive.
