Not Necessarily SoI think that the title of this group would be better suited if it was "I think failed relationships have the potential to change people".
In order for change to come about, first there must be acceptance of responsibility. I'm sure we've all met people that perpetually blame the other party while not shouldering any of the blame for the relationship ending. I know I've come across plenty. In many of those cases I've found that the people years later are still the same and have not grown at all. It's almost as if time stands still for these types and down the road they are left as bitter lonely people blaming the outside world for all of their woes. One must be open to at least the possibility that the blame almost totally lies within our own self in order to truly change. With very few exceptions both parties are always at least somewhat responsible. Acknowledging that and taking ownership of the things that we could have done differently to help instead of hinder I believe is the true path to positive change. It has been for me anyway.
