I can relate to what your saying...
As for some people only wanting to hear about BAD things: People Love that Drama. They like life to be like a soap opera.

It is a good test to see if you're in a one sided relationship.
Like two people rowing a boat and one stop to see if the other one is giving / doing their share

I seem to find those one sided people - That only want to talk about their stuff..... and Never even if I have something to say they don't hear it anyway, or have to leave, get off the phone -

Or even (make me feel) think they are thinking badly of me
Like I'm crazy or something.
