Why do love relationships turn so bitter at the end, and where does my joy really come from?
Joy and misery come from within
There are two ways to come to someone: to extract something from them, or to share something with them. If you are out to extract, it gets terrible and nasty when they close the tap. The source of joy or misery is within you, not in the other person.
If you are out to share, your life will be good. If you are out to extract, when they close the tap it is going to get terrible and nasty.
