I've had the kind of complex life I write about. I was a single mother for 12 years. I'd been engaged. The wedding fell through. I then discovered I was pregnant and opted to have the child on my own. I was a professor. I was in my mid-30s. I could manage it financially.

Usually, Valentine's Day comes and goes with just a day or two of news media attention to courtship and marriage.

Especially around Valentine's Day, it's easy to find advice about sustaining a successful marriage, with suggestions for 'date nights' and romantic dinners for two. But as we spend more and more of our lives outside marriage, it's equally important to cultivate the skills of successful singlehood.

Valentine's Day is a perfect time to reject the idea that the ideal man is taller, richer, more knowledgeable, more renowned, or more powerful.

In my work as a historian and in my relationships as a friend, teacher, wife, and mother, I have come to think that the most useful way to understand the past and make it work for you is to look at the trade-offs and contradictions that, however deeply buried, can be uncovered in every memory, good or bad.

Cohabitation itself doesn't cause ineffective parenting.
