Huh. Interesting because the original post here touched off a bunch of thoughts in me that were a bit opposite of what I was reading.
There are certain things that I *need* in a realationship for it to be successful. If I am to be in a long term relationship with someone I need for them to feel the same way. I need for them to respect me and I need to be able to respect them. I need for them to care about me. Etc. Those are *needs* I have from within a relationship. If those needs aren't met, then I can't remain in that relationship.
I think there's a difference between being needy and needing something. Maybe it's subtle, but it's there for me. Same between being dependent and interdependent.
Dunno. I don't have a lot of time right now to put my thoughts in order, but this one struck me quite forcefully as I read through the thread.
