The confusing emotions that may have developed between you make things difficult for both of you. You project your own emotions onto your partner, which could lead to you feeling wildly and even willfully misunderstood. Sometimes your emotional projections actually help you to understand yourself better and to process your emotions, but this won't be a reliable effect.
In fact, emotional unpredictability may be all you can count on! Your feelings for this person aren't stable; you are either really into them, overwhelmed by how powerful or important the relationship seems, or you are just as powerfully turned off, wanting to get away from them as soon as possible. In fact, instead of just plain liking your lover, you are fascinated by them -- which doesn't bode well for the relationship. Fascination is good for a science project, not someone you might actually love! It could be that you're so drawn to this person not because of the particular, individual characteristics that they possess, but because they remind you of an old relationship -- maybe even of your mother or father. If that's what's going on, you'll definitely have a hard time breaking out of the behavioral patterns that these deeply-rooted emotions toward each other will spur.
