Cool poem.. I also had an imaginery lover, okay she is kinda real, and your poem describes how I feel sometimes.
Like I am in a prison of love that I created because I love someone who is far away, have her on my mind while I am most likely not on hers, but it is faith that I have that maybe one day she and I will be together but I am not sweating it.
Once again, lovely poem, short and sweet.
