I think what attracted you to the flaws, Men are FIXERS!!! I have always dated and even my first wife dealt with issues from her childhood, these issues, we men, cannot fix. My current W has been in counseling since she was 9, 20 years total. She lost her mother to cancer and has not really dealt with it completely. I do believe that these people who have "baggage" can still be in R's and work on themselves but that is for them to figure out, not us.
I am reading the Father Connection which stresses the importance of how kids deal with single parents vs. their parents staying together. So much can happen to children that never get addressed or they never heal from. Those issues follow them the rest of their lives. The only thing they can do is find a way to hide it or heal it.
