I think getting married or being married is not only about Romantic Love. Sometimes it is not about Romantic Love at all. Of course some "chemistry" is essential for long-lasting relationship, but so many other things/factors are equally important. And if course I agree that living with another person is lot more stressful than being single, and yet, for some people being a couple seems to be the thing....
Anyway, I appreciate this piece, Ann. You express your views, feelings and priorities so well that it is hard to disagree with you :-) And there is no need to disagree: this kind of views, feeling, priorities are very personal. It seems to be obvious you've made the decision which is right for you.
