You have to do the hard work of staying alert and honest in this relationship -- honest with yourself as well as with your lover -- because this aspect could lead you to delude yourselves about the true nature of your connection. You idealize your lover from the start, which is dangerous because it sets up false, even impossible expectations that can only lead to disappointment. You're highly sensitive to their moods, and often oversensitive.
You project something onto your partner that's not even there and react with hurt feelings, even tears. Needless to say, if this is a reaction to something your lover wasn't even feeling in the first place, it's confusing at the very least! Blame could become a popular obsession between you if you're not careful -- you accuse each other of having feelings or intentions that just aren't accurate, because pointing the finger is easier than inspecting your own hearts. To avoid this problem you have to remind yourselves repeatedly to be completely open about your feelings, because otherwise, you run the risk of misunderstanding or misinterpreting your partner.
