Engaged, But In Love With Someone Fictional

Ever since I was a kid, I've always developed strong attachments to certain characters in books, movies, etc. But I almost always understood they were fictional and was able to put it aside. As an adult I have a fiance, whom I love very much. But there's a little piece of my heart that can't help but love The Doctor. Yes, that quirky British mad man in a blue box. I know he's just a fictional character, but sometimes I find myself listening for the TARDIS, wondering where he is or if I've been with him in the past and just can't remember (like Donna). I've come up with crazy ideas and constantly find myself dreaming up theories about how he could be real, and waiting for the day he comes for me. I feel ridiculous, but I just can't seem to help myself.
