My flaw is that I care about girls I met in past relationship in a good way, regardless of what they think of me. I don't have feelings for them, they were just people I enjoyed life with and things didn' work out. Many were mature enough about breakups and moved on, and they and I understand that things happend for a reason and it was part of growing up in life.
It was just this girl who took the failed romance to the dark side, as oppose to a romance that understands that we mark our lives by our scrapes with love, and our defeats, rather than simply white-wedding-cake success.
In my book, I just hope she is happy, I really do.
