"I have a wonderful boyfriend. He knows who I am, as much as someone who isn't me can. He knows my little endearing traits, which become annoying at any great length. We have been together for over a month. He is, and has been my best friend for years. We sit together in bed, and read. We have fun together, and we can also do separate things and enjoy each others company. "

Except how long we've been together, this sounds like Tregoweth and me. My best friend for nine years, my boyfriend for slightly over two years, my roommate for slightly less than two years. So, although the plural of anecdote is not data, in my experience this is a profile of a relationship that continues to work at least this long and with no sign of flagging. I hope that's encouraging. Even when one can stand alone, it's nice to have someone who one could lean on if necessary.
