In a relationship, the job is non-reaction. Another word for non-reaction, according to spiritual teacher Eckhart Tolle, is forgiveness. Forgiveness works wonders. As the Good Book says, "Love covers a multitude of sins." Forgiveness doesn't require participation from your significant other. It only requires your participation.
Tolle's first book, The Power of Now is in question-and-answer format. The question (in this case, actually, a comment):
I suppose that it takes two to make a relationship into a spiritual practice, as you suggest. For example, my partner is still acting out his old patterns of jealousy and control. I have pointed this out many times but he is unable to see it. [Italics original]
Tolle's answer: "How many people does it take to make your life into a spiritual practice? Never mind if your partner will not cooperate. Sanity--consciousness--can only come into this world through you." If you wait for your partner to come around, Tolle says, you may be waiting forever.
