How can things get better between two people if one has no clue that something is wrong?

How can two people relate if the attitude of one is, "My way or the highway?"

How can a relationship be mended if one person has cut all communication?

There comes a time to quit trying no matter how much you love someone, whether family, friend or mate.

I am just now learning this after much suffering.

I am certain that I tried my best.
I tried to the point where it would be insane to continue trying.

I can finally let go.

I wish them well, but I will no longer suffer because they are who they are.
