We expect the opposite s*x to be more like ourselves. We desire them to "want what we want" and "feel the way we feel". We mistakenly assume that if our partners love us they will react and behave in certain ways... The ways we react and behave when we love someone. We have forgotten that men and women are supposed to be different. Clearly recognizing and respecting these differences dramatically reduce confusion when dealing with the opposite s*x.
Men continue to expect women to think and react like men, and women expect men to feel and behave like women. Without a clear awareness of our differences, we don't take the time to understand and respect each other. We become demanding, resentful, judgmental, and tolerant. When men and women are able to respect and accept their differences then love has a chance to blossom.
