I used to really feel bad when I expect a person to be there for me, and he/she isn't.
Now, I just don't care. I've realized I can do things on my own, and that a companion isn't necessarily a good thing-- or welcome. Good? Bad? I don't know. But what I know, I realized, is that I've become a trifle undependable as well, as if I expect other people to not depend on me, the way that I do not depend on them.
For now, I'll consider that a good thing. Hope to God I don't feel too lonely :|
