Interesting. That actually reminds me of my behavior as an E5. I will work obsessively on finding a solution to whatever problem I'm interested in at whatever moment, and there's really nothing anyone can do to convince me not to, until I get tired, or realize that it doesn't matter or I'm not going to solve it any time soon.
It's almost like the same inner tension that exists inside us all is perceived or felt differently by each E type, and dealt with in accordingly different ways.
I hope that's not an accidental regurgitation of basic enneagram theory.
I don't mind that she comes to me with her problems, though I find it frustrating when she ignores my advice. It's not that she doesn't take it. I understand she has the right to do as she pleases. But she doesn't even comment on it. I have no idea if I'm helping her or not.
I think she feels different about being left alone, because she'll usually mention to me that she's stressed, which leads me to believe she wants help. Who knows, maybe she just wants to talk about it. Hmm.
