Complicated doesn't even begin to cover it. I'm in this situation now and it's basically ruining my life. Or maybe it's ruined already, because I see no possible way out -- not even just ending the friendship.
Not only is the friendship very close, but inextricably linked with far and away my favorite activity in the world. One that has brought by far the most joy to my life, and one that I have given up a lot to pursue.
I don't even know how I could have predicted or avoided it, either. At first glance, I never would have guessed I would end up feeling any attraction to her at all. In actual fact, what I ended up with are feelings I could have never even imagined I was capable of feeling for someone (I'm 40).
The only thing I could have done differently, I'm afraid, would have been to make damn sure to never get so close to any woman at all.
