Alexander Pope, "Eloisa to Abelard"

How happy is the blameless vestal's lot!
The world forgetting, by the world forgot.
Eternal sunshine of the spotless mind!
Each pray'r accepted, and each wish resign'd;

"Every obstacle presents an opportunity to improve our condition."

 Tips on how to build a healthy love life with your partner.
By Hara Estroff Marano

Never go to sleep angry. Try a little tenderness.
Apologize, apologize, apologize. Anyone can make a mistake. Repair attempts are crucial—highly predictive of marital happiness. They can be clumsy or funny, even sarcastic—but willingness to make up after an argument is central to every happy marriage.
Research has shown that the more roles people fill, the more sources of self-esteem they have. Meaningful work—paid or volunteer—has long been one of the most important ways to exercise and fortify a sense of self.
Enrich your relationship by bringing into it new interests from outside the relationship.
Stay open to spontaneity.
Maintain your energy. Stay healthy.
Recognize that all relationships have their ups and downs and do not ride at a continuous high all the time. Working together through the hard times will make the relationship stronger.

--Make good sense of a bad relationship by examining it as a reflection of your beliefs about yourself. Don't just run away from a bad relationship; you'll only repeat it with the next partner. Use it as a mirror to look at yourself, to understand what in you is creating this relationship. Change yourself before you change your relationship.--

Understand that love is not an absolute, not a limited commodity that you're in of or out of. It's a feeling that ebbs and flows depending on how you treat each other. If you learn new ways to interact, the feelings can come flowing back, often stronger than before.
