Proof that the fact that a relationship is imaginary does not necessarily mean it's easier than real life:

My imaginary girlfriend and I broke up yesterday.

Our relationship had been less than stellar from the start, and we actually stopped really being lovers long ago, and became just good friends with an occasional inconsequential spark of romance. So technically we "broke up" long ago. But all this time, I still considered her the closest thing to a lover I had. The possibility of us ever getting back together is gone now.
She found someone else. I hope she will be a better lover to her than I was.

Believe me or not, but this has been largely beyond my control. My characters are developed to a point where they practically have a will of their own, and according to their personalities they can make their own decisions that may or may not match with what I would have liked.
I was in fact rather shocked to realize this turn of events. It took me a while to liberate myself of the feeling of having lost something very dear to me, and I'm still not really sure if I've come to terms with it by now. Vanessa and I were so close together, I considered her a part of myself. (I know, that's an ironic thing to say in my case. But I mean that even in the more common sense.)

I'm happy for the two of them. I'm happy for her, that she's found new love. I acknowledge without a second's hesitation that her new lover deserves her much more than I do.
I just don't want to be alienated from my best friend. That is by now the only thing that worries me.

Thank you for listening.
