I have a theory (a short story)

I have a theory. A theory that falling out of love is simply a myth, that once you've shared your thoughts, dreams and moments of fate with the one you love, there's no going back. Love; funny thing, isn't it? "Before I met him, I wasn't really sure of anything going on in my life, but now, I'm at least sure on one thing; I am absolutely, categorically in love with Lucas Morgan." "Rosie Summerville, I am so in love with you. You make me happier than I ever thought I could be." "All I can do now, is hope and pray, pray that my prince will come back to me." "My Luke, my prince and my soulmate" "Before I met you, I didn't even know who I was, but then you came along and showed me exactly who that was." "My little sunshine, I love you forever and always, never ever forget that, and I'm sorry our story had to be cut so short" "This right here, is the reason for my theory."
