My parents just celebrated their 70th anniversary. My husband and I just celebrated our 46th. Staying married is not easy. I once wrote an article about Choices and Trade-Offs in relationships. We each make choices about what we can and cannot tolerate, and with those choices come trade-offs, something that we feel is worthwhile. I'm being vague, but each person who has been in a long-term relationship knows what I'm talking about.
