In Praise of Unavailable Men

Unavailable men are a chance for a relationship with clearly defined boundaries and in a way offer women who are afraid of commitment or intimacy a chance for love and friendship that gives them reason to rejoice and get jazzed about life in general while keeping them 'safe.'
Right now I have some friends and acquaintances on the Internet whom I find interesting but the only problem is that they are far, far away and some are in a committed relationship. Also, it is verboten to fall in love with someone at work. So, it is easy to be friends while putting up screens or setting limits with others and with our own feelings. I wish I could write a song to unavailable men. Maybe I could come up with a poem. Unavailable men are so much more attractive. They are so much more exciting and interesting. But what if an unavailable man were to become available, would that spoil it for me? Would the attraction go away? It's kind of along the lines of 'absence makes the heart grow fonder.'
