Apologies for probing you on this .. Is it you that thinks it's an issue of codependency or have you been told this by another?
My upbringing wasn't great and pregnent at 15 .. I've been told (once) i was codependent, but now away from the situation, i realise a lot of projection was going on or i'm just an asshole that brings out the worst in people .. If i love someone then i want to spend time with them .. Thats not codependency, that's love but i may be wrong.
I'll check out the film though, out of interest .. Maybe i could learn something.
