You keep landing in fairy-tale relationships, but not in the good way. You bought the myth of Love at First Sight hook, line and sinker, but there's no room for reality in your dream world. You were in love with love, not with your lovers at all.
In fact, you never even really had an idea of who they were at all. You projected your dreams and fantasies onto a blank surface; what you thought you loved was only your own false vision. Somewhere in the back of your mind you knew that you were living in a fantasy, but you kept your eyes closed and just kept on dancing, hoping the music would never stop. Sorry, but it's not that easy. True love requires true vision and the occasional reality check. Next time, keep one hand firmly on the wheel of your relationship. Double check that you see what's there and not what you want to be there. You've got a lot of love to give. You can find someone who is actually a beautiful match for you, with much potential for growth in the relationship and as individuals. It's just going to take a lot more work before you hit the promised land.
