I know that they're not feeling well, but you know, when I ask them "What's wrong?" or "Do you want to talk about it?", they reply with "Not really"
Under a lot of other circumstances, I would've just dropped the topic- If they don't want to talk about it with you, there's nothing else you can do. It could be because they don't trust you enough, or that they simply aren't mentally prepared themselves to let you know about it just yet.
But, what if you knew that part of the reason why they felt under the weather was your fault? Your fault not in the sense that you did something wrong to them directly, but rather they weren't allowed to have ever been as close to you as they should've. Then what?
It's hard for me to really demand that people like that under that situation to rely on me: as much as I want them to rely on me, I know that I myself have close to no power to help them. Not to mention, if the roles were reversed, I would've tried everything in my power to prevent myself from telling them. I don't want to burden them with my problems. And yet I want them to want to rely on me? That's too much.
Am I a hypocrite? Hm, maybe.
