Push or Pull?

I just don't understand what people want, especially this one person.

To be claimed as a close friend, both shall be vulnerable to each other, no matter the stories, adventures, misadventures or whatnots.

But when you suddenly draw a line on something that helps overcome your significant other's concern (and without apologising as courtesy goes) just puts it off right there.

I might not know what he's thinking.
It may be the best for me not to know.
It may also be the best for him to not really dwell into one's concerns (and probably problems, I don't know).

Maybe I'm just having that split-second anger reflex in my emotions.
Maybe I'm just being overly emotional.
Maybe I'm overreacting, overthinking, yada yada..

But maybe I'm not.

I'm just concerned over my dear close friend.

But when you shut that door so unexpectedly, so suddenly..

I won't lie,
But you did cut me deep
Without me knowing why.
