When I broke up with my previous partner in 2007, my uncle told me to live like Katharine Hepburn--keep the guys close, have them visit often, but never let them move in or give yourself away. A few years later I met someone though and we've been together for 7 years. Then in his mid-60's he had to eat his own words cause he met the love of his life and they've been happily together for 5 years, now moving in together.

I've always enjoyed being single. Truly being happy single seems to be a prerequisite for a good relationship. Then when the right person comes along, you're not surveying them to match some blueprint or expectation of the long term or fill a void that will ultimately impact the relationship's success; it just happens organically.
