Err, New Guy? Just to poke x3
1. Why people don't say things up front is because they value the status-quo relationship enough they don't feel it's worth risking it to break it apart. Tell a person who had a case of being bullied to be an idiot for not fighting back, see the conflict that ensues.
This approaches Social Conformity--but the example is....
extremely off and out of place. [I mean seriously. Why would you tell a person he's an idiot because {didn't do x} o_O]
Why people don't say things up front is because of many reasons. Some do it out of respect. Some expect the other to read in-between the lines given the context of what's being said [as I doubt everything JB mentioned here is the whole story; its his portion of it but its not whole given the descriptions in the gaps]. Some do it because that's how they reason things. Some do it due to personal expectations and infer that the other recalls what's done and said.
Conformity is just one cause.
And...um, I think there's a certain spin to your numbered list of causes and answers which may cause a lot more trouble if taken as-is by itself.
One can mention they're sick because they're legitimately sick. Whatever else has occurred may have just passed their mind
innocently and without malevolent intent for you to not have known it. If it is important to you--make it known instead of expecting it to be known to you due to vagueness of clarity of value. [which seems to be the cause of JB's outburst].
There is no such thing as true love, as the number of divorces can attest.
NG O_O Srsly.
There is such a thing as true love; the presence of divorce does not occur from the lack of true love, or otherwise. Divorce occurs from a lot of reasons >_> <.<
The existence of such a concept must not be based on the existence of another, similar yet pertinent concept when both can exist solely by themselves.
Point is: There is such a thing as true love...and the thinking up there about thinking it that way won't really describe it well.
Everything else is totally K though. Don't hate the girl. You may have shortcomings you're currently not aware of, either. And of course, you wouldn't want to be hated because you weren't aware of them.
It's the fun of the complexity of perceptions. They're complicatedly simple. :3
But its confusing when one pushes away a person just as much as they 'don't matter in your life' as if you judge them only like...that.
It's like giving them a basis solely by what you feel instead of who they are. o_o
