I saw an article or something on TV about it and wanted to know more.
I read the book "Codependent No More" and saw myself in the stories
of others. It's hard to explain, but it's when you have an unhealthy
dependence or involvement with another person and you end up losing
yourself, much like spouses are negatively affected by the alcoholic
only without the alcohol. That's my understanding of it anyhow. If
you read the book you'll be better able to tell if you are.
