Not to beat a dead horse, but I think that in a healthy relationship I can rely or depend on the other person. No one is an island. I am independant, but I would prefer to be a part of a team. I like cooking for someone and having that someone worry about the tread on my tires. I do not think this is co-dependant. I think it is a good relationship.
Like all things, I think that independance can be carried too far as well. I have been and seen others become defensive about every show of dependance. In extreme anything is bad. To ME, a balance of dependance and independance works. I can still be soft and tough.
HUGS to all
